A man bit off part of a Denton police sergeant's ear after a traffic stop late Friday, authorities say.

Police pulled over a driver about 11 p.m. on suspicion of driving while intoxicated on Interstate 35E near North Texas Boulevard.

The man, who was identified as Christopher Rogers, 45, refused to get out of his vehicle after officers asked him several times to do so. When officers tried to get the man out of the vehicle, Rogers punched an officer in the face.

Police said Rogers began biting a sergeant once officers got the man on the ground. Part of the sergeant's ear was bitten off, and he also suffered other injuries to his head, police said.

Rogers was charged with assault on a peace officer, aggravated assault, resisting arrest and driving while intoxicated, police said. He was booked into the Denton city jail. Records showed he was no longer there on Sunday.

A spokesman for the Denton Police Department said the sergeant who was injured was recovering at home. His name was not released.
