Authorities in Florida say a school bus driver has been arrested and charged for sexually assaulting four special needs students.

The Polk County Sheriff's Office initially charged Carlos Ojeda, 72, of Haines City, with eight counts of capital sexual battery involving two female students under age 12.

Late Friday, authorities say Ojeda identified two additional victims, both under age 12, and was charged with two more counts of sexual battery after detectives interviewed the two girls. They told detectives they were sexually abused by Ojeda while riding his bus.

Ojeda is who is being held in the county jail without bond. He drove a school bus for three different schools. WFTS-TV/ABC Action News in Tampa reported he had been employed by Polk County schools since April 2007 and has been suspended without pay.
