SARASOTA, Fla. (AP) - A Sarasota Sheriff's deputy lost his job over a confrontation with a special needs child on a school bus last month.

Deputy Mark Perrin was fired Wednesday following an internal investigation into allegations that he threw the 17-year-old girl onto a school bus and threatened to shock her with a Taser. The incident was caught on videotape.

 A school bus aide called 911 about 3 p.m. on Dec. 15 to report an attack by a student. Perrin arrived and the girl didn't follow his orders, resulting in the confrontation. The teen was taken to a hospital for a mental evaluation.

Witnesses on the bus complained about the deputy's aggressive actions and he was suspended that afternoon.

Perrin was hired in June 2001 and earned about $59,000 a year.
