Shortly before 7 p.m. Wednesday, police responded to a suspicious vehicle call on Cambridge Park Court. Several residents said an ambulance was speeding through the subdivision and knocking down mailboxes.

Officers talked with a man who had a large laceration on his leg, which he said he got after jumping off the back of a moving ambulance, police spokesman Cpl. Deon Washington said.

The man, who originally was driving the ambulance that belonged to private company Med Care EMS Transport, said he and Lathon worked for a Buford company and had been arguing all day, Washington said. The men went to the subdivision to pick up a person and realized they had left their wheelchair at the hospital. That caused additional tension, the man told police.
