FT. LAUDERDALE (CBSMiami) – Broward transit officials are standing behind the actions of a bus driver after a teen was attacked both on and off a county bus.

The incident on Sept. 5th started like any other bus ride, filled with noisy passengers, that’s until the bus pulled up to the stop at the 1500 block of West Sunrise Blvd.

Four teens get off, then one steps back on as the driver screams for him to stay away.

Surveillance video shows the victim, 17-year old Tyreek Westby, being dragged off the bus and onto the sidewalk while the door slams closed behind him. Immediately the four teens punch and kick him.

Moments later Westby broke free and tried to run away, only to be caught, body slammed to the ground, and kicked and punched by the violent mob of teens again. Finally, the attackers run off with his iPod and ear buds, leaving him dazed.

Westby then tried to get back on the bus, but the driver refused to open the door. Several passengers tried to kick the door open to no avail.

A transit spokesperson said the driver followed procedures and reported the incident to the proper authorities.

The county says the driver did not see the same things that were captured on the surveillance video.

She only heard the shouts and screams and did not open the door because she didn’t know if the victim or attackers were banging.

The county said the driver will face no disciplinary actions.

On Wednesday, police announced a second arrest in the case. He was charged with aggravated battery causing bodily harm. The first teen suspected in the beating was arrested November 7th. He was charged with strong armed robbery and aggravated battery causing bodily harm.
