BROOKHAVEN, N.Y. (CBSNewYork) — A Brookhaven man has been arrested for allegedly threatening to kill a marina security guard.

The security guard had turned down the group because they did not have the proper key to enter the marina, police said.

Lippens allegedly threatened the security guard and indicated he would come back with a gun, according to authorities.

He left on foot but came back about 15 minutes later riding a dirt bike with what appeared to be a handgun, police said. He threatened to kill the guard before riding away, police said.

Police found Lippens at his home on Bond Lane.

Lippens tried to run from the home but officers were able to detain him after a brief struggle, police said.

Investigators found ammunition, loaded assault rifles, Kung Fu stars, knives, a bullet proof vest and more than 20 marijuana plants at the home, police said.

Lippens has been charged with menacing, criminal possession of a weapon and unlawful possession of marijuana.

He pleaded not guilty to the charges on Monday. Bail has been set at $750.
