Princeton police officers are on the lookout for a serial groper.

Authorities say that the suspect groped at least three women this year.

The latest incident happened on Saturday just before 10 a.m. Police say that the suspect groped a 24-year-old woman on Linden Lane. The victim described the suspect as a Hispanic man with medium-length black hair, short in height and a stocky build. He was wearing a neon yellow polo shirt and jeans.

Police say that they believe the same man is responsible for acts of criminal sexual contact in February and in June.

Police say that the incidents have not been violent in nature, but are disturbing.
