A Piscataway Township police officer has been arrested and charged following a sexual contact investigation in South Plainfield, according to information released by the Middlesex County Prosecutor’s Office.

Authorities say the investigation began on April 30, 2025, after reports surfaced that a man was following young females, including a child, around a South Plainfield store while visibly aroused.
Surveillance footage captured some of the troubling behavior, and investigators later learned the same man had engaged in similar conduct at another nearby store.
The suspect was identified as 37-year-old Wesley Kliwinski, a Piscataway police officer who resides in Hamilton, NJ.
Kliwinski was taken into custody without incident on May 1, 2025, and charged with third-degree endangering the welfare of a child by engaging in sexual conduct, fourth-degree criminal sexual contact, and harassment, which is considered a petty disorderly persons offense.
After an initial appearance in Superior Court, Kliwinski was released from the Middlesex County Adult Correctional Center.

The investigation remains ongoing, and anyone with additional information is urged to contact Detective Thomas Rutter of the South Plainfield Police Department at 908-226-7663.
