It's usually the lifeguards who calm down tense situations on Jersey Shore beaches by rendering aid to those in trouble.
But authorities allege an Ocean City lifeguard was behind a very tense situation on the shore resort's 36th Street beach on Tuesday.
Zachary Kranefeld, 21, of Millville, was charged with possession of a prohibited device after a co-worker tipped off police to the fact he had a homemade smoke grenade in a car parked at 36th Street and Central Avenue, Ocean City Patch reports.

The 36th Street beach, as well as beaches from nearby streets, were evacuated Tuesday afternoon as police blocked off roads and an Atlantic City bomb squad came in to detonate the device on the beach.
Kranefeld was processed on the weapons offense and released.
