A 56-year-old man was arrested on charges of assault and weapons possession after a bizarre encounter on a street in Roosevelt early Wednesday, police said.

Joseph Dempsey, of 28 Grenada Ave., Roosevelt, was arrested after he attacked two men walking on Nassau Road at 1:28 a.m. -- a walk during which the men spotted Dempsey attempting to light rags stuffed into two glass bottles, according to Nassau County police.

Dempsey yelled "a verbal statement" at one of the two men, then stabbed him in the left wrist with a bayonet-style knife, police said.

Police said the victim, 43, had been walking along Nassau Road with a 56-year-old male friend when the assault occurred. The friend was not injured.

Police said that after the assault, the two men tried to get away from Dempsey, crossing the street and calling police. Dempsey followed the two, however, police said.

All three were still at the scene on Nassau Road when police said they arrived, arresting Dempsey and recovering the knife and six glass beer bottles. The bottles were stuffed with cloth wicks and each contained a liquid believed to be an liquid accelerant, police said. Police are awaiting the results of lab tests to confirm the type of liquid involved.

Dempsey was charged with second-degree assault and six counts of third-degree criminal possession of a weapon.

He faces arraignment Wednesday in First District Court in Hempstead.
