Four young girls were allegedly groped by a pack of men at a popular Long Island water park, authorities said this week.

The group of men “subjected female juveniles to unwanted physical contact” while in the wave pool at the Splish Splash Water Park in Calverton on Aug. 21 around 4:30 p.m., police said.

The victims include two 11-year-olds, one 12-year-old and a 13-year-old, the Riverhead Town Police Department said.

According to cops, the young girls were at the water park for a YMCA trip.

Camp counselors were notified of the incident and several people were escorted out of the facility, police said.

Eight men and a woman who were captured on surveillance footage at the park are now wanted for questioning by police in connection to the incident.

Suffolk County Crime Stoppers is offering a cash reward of up to $5,000 for any information that leads to an arrest in the case.
