If you believe that your brother poses a danger to your mother or anyone else, it's essential to take action to ensure everyone's safety.
If you call the police to report the abuse, they will assess the situation and take appropriate actions based on their investigation and the laws in your country. The response will depend on various factors, such as the severity of the abuse, the evidence available, and the specific laws and procedures in your region.
In many countries, the police have the authority to detain a person if they believe that person poses a threat to themselves or others. However, the ultimate decision on whether your brother will be locked up or taken into custody will be based on the police assessment and their judgment of the situation.
When you call the police, it's essential to provide them with accurate and detailed information about the abuse and your brother's condition, such as his diagnosis of paranoid schizophrenia. This can help them better understand the situation and respond accordingly.
Additionally, it's essential to inform the police if your brother has a history of mental illness, as they may take this into consideration when dealing with the situation. They might involve mental health professionals to assess the situation and provide appropriate support.
Remember that laws and procedures can vary significantly from one country to another, so it's best to consult with a legal expert or a local authority to get accurate information about how the police would handle such a situation in your specific region. Also, consider reaching out to mental health support organizations for guidance on dealing with a family member who has paranoid schizophrenia and is exhibiting abusive behavior. They might be able to provide you with helpful resources and advice.
