There is extra motivation in this case to get this week's criminal behind bars.

"The victim is an elderly male that is disabled and was unable to protect himself," Chattanooga Police Sgt. Victor Miller said.

If our suspect will go so far as to push an older man down at a bus stop, what is his limit?

"It was right before Thanksgiving in November; it was about noon," Sgt. Miller explained."The victim is on a CARTA bus. As he exited the bus and started walking home, the suspect was also on the bus with him, got off the bus at the same location and then pushed him to the ground and robbed him."

Thanks to security cameras in CARTA buses and at bus stops, we get a look at the bad guy.

"The quality of the video is not great, but you should recognize him," Miller said. "Also, the clothing that he's wearing. It's a black male, he's approximately 5'8", about 200 pounds. He's wearing gray jogging pants and a dark blue or black hoodie and he has a jacket over it."

The attack happened in the 2100 block of Oak Street in East Chattanooga. The criminal may be a frequent bus rider, but this was likely not his stop.

Once he knocked the man down and took his wallet, the crook ran away.

"The suspect is a younger black male and the victim is an older male that, you know, was unable to take care of himself," added Miller. "So, that's the reason why we're bringing it to Crime Stoppers, because it's very important for us to get this person. If they're going to take advantage of one of our community members, we want them off the streets so they don't offend again."

If you know the suspect, or have seen him around and might know where he hangs out, we want to hear from you. Up to $1,000 reward is available.
