Bond was set at $150,000 for two of four teens who allegedly boarded a CTA bus, shut off the engine, beat the driver and robbed at least one passenger, authorities said.
 
The four — two 17 year olds and two 13 year olds — are alleged to have boarded the bus in the 600 block of East 71st Street about 7 p.m. Saturday after disabling the engine by hitting a switch on the side of the bus, police said.
 
Love, of the 700 block of East 90th Place, was charged with a misdemeanor count of battery and a felony count of robbery. Williams, of the 7200 block of South Evans Avenue, was charged with a misdemeanor count of battery and a felony count of attempted robbery, police said.
 
On Sunday, a judge ordered Love and Williams held on $150,000 bond. Prosecutors said Love punched a passenger and stole an iPod, watch and seven dollars, while Williams attempted to rob a passenger by going through their pockets.
 
They then allegedly beat and punched the bus driver, police News Affairs Officer John Mirabelli said. The two 13 year olds have each been charged with a count of misdemeanor battery.
 
Grand Crossing District tactical unit officers responded immediately to the call and arrested two of the teens at the scene, Mirabelli said. Two others attempted to flee the area but were soon caught by police.
 
A witness on the bus, along with the victim, were able to identify the four as the offenders, Mirabelli said.
Prosecutors said Love has some juvenile arrests, including a residential burglary.
