The family of 59-year-old Bridgeport bus driver Sandra Diaz is demanding justice after she was attacked while on the job.

Her son, 33-year-old Axel Colon, has muscular dystrophy and has been in a wheelchair since he was 12.

He said he is closer to his mom than he is to anyone else.

She is not only his primary caregiver, but she's been a Greater Bridgeport Transit bus driver for the past 20 years.

Colon shared with News 12 Connecticut that the attack happened outside of VIP Carwash on Main Street Friday around 5 p.m.

Police say the suspect, 35-year-old bus passenger Adrian Carter,  grabbed Diaz, dragged her off the bus, threw her to the ground and repeatedly assaulted her for several minutes.

"My mother was brutally beaten. This guy — I don't even want to consider him a guy. He's a savage," Colon said.

Diaz was treated at Saint Vincent's Medical Center for a concussion, a broken finger and contusions all over her body.  

Colon said it would do his heart good if GBT would consider adding a security guard to every bus.

Greater Bridgeport Transit CEO Doug Holcomb said there's no walking back this kind of attack, especially when the victim is a beloved member of the GBT family.

"The most important message is cherish the drivers and take care of the drivers because they've been out there through the pandemic. This particular operator's been with us for 20 years -- a well-liked operator in the community," Holcomb said.

Holcomb also told News 12 Connecticut that each bus now has a dozen cameras and GBT's safety protocols are extensive.

Colon, however, said he'll never get over the terror of learning his mother was beaten in broad daylight and does not want her to return to work.
