A city police officer from Suffolk and his K-9 partner were injured making an arrest following fights among four women on a subway platform Tuesday, police said.

Officer Vincent Tieniber, 36, suffered a sprained wrist, and Bear, a German shepherd member of the Transit Bureau's K-9 unit, was kicked twice in the mouth, police said.

Bear suffered two cracked teeth, two others chipped, a cut to his tongue and scrapes on his snout, police said.

Bear was treated and released from the Animal Medical Center at 510 East 62 St., Manhattan.

Tieniber was treated and released from Beth Israel Medical Center in Manhattan.

Tieniber said in a new release that while Bear was injured, he "kept the woman's foot in his mouth, and held on until I could handcuff her,"

The altercation took place about 11:15 a.m. on the southbound platform of the No. 4 subway at 59th Street and Lexington Avenue, police said.

The dog's attacker was charged with injuring a police animal, the top charge among four that included disorderly conduct, resisting arrest and obstructing governmental administration.
