Yes, an individual on parole in another state can be arrested while visiting a family member in California if they violate the terms of their parole or commit a new offense. Parole is a supervised release program for individuals who have been released from prison before the completion of their sentence. When someone is on parole, they must follow specific conditions and restrictions set by their parole officer and the state parole board.
If the individual violates any of the conditions of their parole while in California or commits a new crime, law enforcement can arrest them. The state in which the person is on parole will typically work with the authorities in California to coordinate their arrest and, if necessary, arrange for their return to the state where they are on parole to face consequences for the violation.
It's essential for individuals on parole to understand the terms of their release and to comply with all the conditions set forth by the parole board to avoid any legal troubles. If they plan to travel out of state, they may need permission from their parole officer or need to inform the relevant authorities about their travel plans in advance. Failure to follow these rules can lead to serious consequences, including arrest and possible reincarceration.
