Authorities are investigating an attempted sexual assault of a woman in Belmont Lake State Park on Friday, state officials said Saturday.

The State Park Police, which patrols the 463-acre park in North Babylon, are working with local law enforcement to investigate the incident, which happened around 9 p.m., a state Office of Parks, Recreation and Historic Preservation spokesman said in a statement.

State officials did not release additional details about the attempted attack but, according to the Police Benevolent Association of New York State, the suspect “forced her into a wooded area and attempted to assault her. She managed to fight her way out of the attack and report the crime.”
