He was arrested Monday near his home and charged with three counts of false imprisonment, one count of bribery, two counts of assault under color of authority and four counts of sexual battery by restraint, all felonies.

Prosecutors said the crimes happened in less than a three-week period during traffic stops. In two of the instances, he fondled the women.

The incidents happened between July 28 and Aug. 15 in 2014. The victims were between 20 and 28 years old.

The investigation started in September 2014. That was when the Monterey Park Police Department asked an outside agency, the Long Beach Police Department, to look into the allegations. On Monday, Sanchez was arrested.

If convicted, Sanchez faces more than eight years in state prison.

A call to the defendant’s attorney for comment has not been returned.
