The NJDOT site said only that there was police activity south of Sandy Hook State Park, and that the park was closed as of 2:25 p.m.
A spokesperson from the National Park Services said the park was closed because it was at capacity, which is not a state park, but a part of Gateway National Recreation Area.
Daily Voice has reached out to the NJ State Park police for details.
