Police are looking for a man who robbed and assaulted a woman on Middle Neck Road in Great Neck early Tuesday, Nassau County police said.

Police said the 39-year-old woman was walking north at 4:15 a.m. when a man came from behind, covered her mouth, brandished a knife and demanded money.

After the woman told the man she had no money, he went through her jacket pockets, taking two cellphones and other items, police said. He then touched her inappropriately, police said in a news release.

When the victim tried to bite the man’s hand, he fled south on Middle Neck Road.
