Arrested

The police have been known to arrest burglars but they do not arrest playable Sims in The Sims or The Sims 2.

When a Sim calls a false alarm to the police they get a warning or fined. The police will also pick up runaway teens or teens out after curfew  and return them home.

In The Sims 3, a Sim can get arrested if they work in the criminal career. While in jail, the Sim can choose to sit there, work out, meet friends, or play dominoes. The arrested Sim can get out of jail when his bladder is low. The Sim in question will walk out of the jail and wet himself. But he won't go back in.
