Arrests and searches in Berikon are governed by Swiss federal criminal procedure law together with cantonal rules of the Canton of Aargau. Criminal investigations, arrests and searches are primarily carried out by the cantonal police and supervised by the public prosecutor's office. Federal law sets key procedural safeguards - for example rights during arrest, limits on detention and rules on judicial review - while cantonal authorities handle day-to-day policing and investigations in Berikon.
The general aim of the law is to balance effective crime investigation with protection of individual rights. Police may detain persons and conduct searches when there are reasonable grounds for suspicion or immediate danger, but most intrusive measures require legal authorization from a prosecutor or judge unless there is an urgent exception.
Criminal investigations often create significant immediate and long-term consequences. You may need a lawyer if any of the following apply:
- You are arrested, detained or formally suspected of an offence. A lawyer protects your rights during questioning and detention and advises on whether to answer questions or remain silent.
- Your home, vehicle or electronic devices are searched and material is seized. A lawyer can assess whether the search was lawful and seek the return or suppression of unlawfully obtained evidence.
- You are asked to provide statements, fingerprints or DNA. Legal advice helps you understand your obligations and potential consequences.
- You face interim measures such as travel bans, bail conditions, or protective orders. A lawyer can request modification or challenge such measures in court.
- You cannot afford a lawyer. In many criminal matters the court can appoint defence counsel or provide legal aid where the case and your financial situation justify it.
Key points to understand about local practice in Berikon and Canton Aargau:
- Responsible authorities: The cantonal police of Aargau conduct investigations and make arrests in Berikon. The Staatsanwaltschaft (public prosecutor) of Canton Aargau supervises investigations and files charges. Courts of the canton decide on pre-trial detention and interim measures.
- Basis for arrest and detention: Police can arrest people when there are reasonable grounds to suspect a crime or when someone is caught in the act. For continued pre-trial detention, a prosecutor or judge must apply legal standards and make a decision. Swiss federal procedure law requires that detention and major coercive measures be subject to judicial review.
- Searches and seizures: Searches of private residences and seizure of evidence generally require judicial or prosecutorial authorization. Exceptions are permitted in urgent situations - for example to prevent destruction of evidence or to prevent danger to people. Vehicle searches and searches of persons during arrest have specific rules.
- Procedural rights: Persons arrested or searched must be informed of the reasons for the measure, have the right to remain silent, the right to a lawyer and, if necessary, the right to an interpreter. If you are unable to pay, legal aid or appointment of a public defender may be available depending on the seriousness of the case.
- Challenging measures and remedies: If an arrest or search is unlawful, affected persons may raise objections with the prosecutor, request the exclusion of unlawfully obtained evidence in court, or file a complaint with supervisory courts. Civil claims for damages are also possible in cases of unlawful conduct by authorities.
Yes. Police may arrest someone without a warrant if they are caught in the act, there are reasonable grounds to suspect they committed an offence, if the person poses a flight risk, or where immediate action is necessary to protect public safety. However, continued detention or more intrusive measures require review and authorization by the prosecutor or a judge.
You have the right to be informed promptly of the reason for the arrest, the right to remain silent, the right to contact a lawyer, and the right to an interpreter if you do not understand the language used by authorities. You should also be informed of any custody conditions and expected procedural steps.
Generally, searches of private homes require authorization from the prosecutor or a judge. Police may enter or search without a warrant only in urgent situations - for instance to avert immediate danger or to prevent destruction of evidence. If police rely on such an exception, they should later justify the search in writing to a competent authority.
The law requires that detention be reviewed without undue delay by a prosecutor or judge. In practice, an arrested person must be brought before prosecutorial or judicial authority within a short legally prescribed period so that the necessity of continued detention can be assessed. If extended pre-trial detention is proposed, a judge must decide on that measure based on statutory criteria.
No. You have the right to remain silent. You should discuss with your lawyer whether answering questions is in your best interest. Silence cannot be used as the sole basis for conviction, but prosecutors and courts will consider the totality of evidence when assessing a case.
Yes. Police may seize electronic devices if they are relevant to an investigation, but seizure and examination of data are subject to legal safeguards. Accessing stored electronic data often requires specific authorization from the prosecutor or a judge, especially for private communications. If devices are seized, you are entitled to be informed and to seek legal review.
Make a clear record of what happened - names, badge numbers, time, place and any witnesses. Contact a lawyer quickly to discuss options. You can raise objections with the public prosecutor, request exclusion of unlawfully obtained evidence in court, and, where appropriate, file a complaint or civil claim against the authorities.
Swiss courts assess whether evidence was obtained lawfully and whether admitting it would violate procedural fairness. Courts may exclude unlawfully obtained evidence or attach less weight to it, but outcomes depend on the specifics. A lawyer can challenge the use of such evidence during proceedings.
Yes. In many criminal cases, if you cannot afford a lawyer and the case involves potential serious penalties, the court can appoint a defence counsel or grant legal aid depending on cantonal rules and the circumstances.
