EVANS, N.Y.: Police say a New York man bit off part of another manís ear during an unprovoked attack.

Police in the town of Evans, southwest of Buffalo, say they shocked John Pawlowski with a stun gun Tuesday when they found two men struggling on the front lawn of a home.

The 31-year-old was taken to a hospital for a mental evaluation and charged with assault, reckless endangerment and harassment.

Itís unknown whether he has a lawyer. A phone listing isnít working.

Police say Pawlowski bit a groundskeeperís face for no apparent reason, tearing off skin and part of his ear.

Pawlowski served six months in jail on a weapons charge in 2007 after he threatened Evans police officers with a loaded handgun after a high-speed chase.
