Phoenix police are looking for a robber armed with a sawed-off shotgun hitting fast food and sandwich shops in the Ahwatukee area.

Police describe the man as being heavyset, around 5 feet, 10 inches tall and between 210 and 240 pounds, with a pot belly.

Victims have described him as wearing all black, including a black beanie and wearing sunglasses during the late-night robberies.

Police think he may have struck again Monday night, hitting a Papa John's pizza, according to KNXV-TV in Phoenix.

Sgt. Frank Matsko says police have increased their patrols, but adds there are a lot of restaurants and fast food businesses in Ahwatukee Foothills.

Anyone with information can call CrimeStop at (602) 262-6151 or Silent Witness.
