Entrapment

Entrapment is inducementInducement: trap or trick or persuade or offer help to commit a crime, especially by authorities, to get a conviction.Concise Oxford Dictionary p451. The implication is that the person might otherwise have been unlikely to commit the crime. In some countries, entrapment is a possible defense against criminal liability.

Another similar term is agent provocateur, an older French term for the person who does the inducing. 

A sting operation is a more sophisticated way to trap criminals. It usually involves leaving a bait, and filming or catching whoever takes the bait.
