A man died after falling from a wall when an officer used a Taser during a foot chase Thursday night, DeKalb County police said.

Police were involved in a robbery suppression detail when they conducted a traffic stop near the Highlands of East Atlanta complex on Flat Shoals Road, DeKalb Assistant Police Chief Brian Harris said.

During the stop, an officer asked the driver to step out of the vehicle after he said he had a weapon. As the officer secured that weapon, the car’s passenger fled, Harris said.

After a short foot chase, an officer used a Taser on the fleeing passenger as he tried to climb an 8-foot wall to get away, Harris said. The man fell over the wall. Officers then went to the inside of the apartment complex and handcuffed the man, who appeared to be unconscious, per police protocol, Harris said.

He said EMS was called and the man was transported to Grady Memorial Hospital, where he died of his injuries.

The Georgia Bureau of Investigation is handling the case.

The is cellphone video of the incident, which will be turned over to the GBI, Harris said.
