Huntsville police are looking for a man who they say has robbed several people in downtown Huntsville in the last month.

Police released video Monday of a man who they said has committed several robberies in the parking lot of the shopping center at Church Street and Cleveland Avenue. The man has used a knife or handgun in all the robberies, police said.

The robberies have taken place at different times of the day, police said. The first took place March 18 at 9:30 p.m. The second happened March 28 at 1:30 p.m. The third took place the same day just before midnight, and the most recent was on March 29 at 6:40 a.m.

The man is in his mid 20s or early 30s, about 5'10" and 200 pounds, police said. He wore a dark gray hooded sweatshirt and light gray sweat pants in all of the robberies.

Each time the robber ran west on Cleveland Avenue into a wooded area, police said.

Anyone with information about the suspect is asked to call the Huntsville Police Department at 256-722-7100.
