Metro Transit Police have a message for would-be thieves: if you're on a Metro train, the next person you rob could be an officer.
In an effort to curb crime, Transit Police are trying a new decoy operation.
The News 4 I-Team got access to video showing some of the arrests.
In one video, a man appears to be passed out on the platform, a perfect target for thieves. But it's really an undercover officer, and the woman that picked his pocket was taken into custody by officers waiting nearby.
In the last two weeks, Transit Police said more than 70 percent of reported robberies involved an undercover officer.
