GULFPORT, Fla. (AP) - Three teens who brutally beat a 13-year-old student on a school bus in Gulfport have been sentenced to probation and community service.
    
A Pinellas County judge sentenced the three teens Thursday after they pleaded guilty to aggravated battery. One teen also pleaded guilty to a robbery charge.
    
On July 9, authorities say the victim was attending summer school at Lealman Intermediate School when two of the teens tried to sell him marijuana. He said no and told a teacher.
    
Later that day on the bus, detectives say the two teens from earlier, plus a third boy, kicked and stomped the victim about 23 times. One of the attackers took $5 from the boy.
    
The beating was captured by a surveillance camera on the bus. The bus driver radioed for help, and the attackers were arrested a short time later.
