Fontana police are searching for a serial rapist they believe may be posing as a police officer.

The suspect is described as a Latino male in his 20s. Police say he has assaulted at least three different times.

Officials say he dressed as a referee and wore a sheriff's deputy ball cap in one case.

He could be using that to gain the victim's confidence, posing as law enforcement perhaps.

The most recent victim was just 15 and walking home from a fast-food restaurant.
