TULSA, Oklahoma - Tulsa police on Saturday picked up a man after he reportedly attacked a Subway worker inside the Walmart near Woodland Hills Mall.

They said the man got upset and hit the clerk in the head with a sandwich.

Police tracked down the man nearby, and said he appeared to be having some kind of a medical problem, so they called EMSA.

"We're just mainly concerned with the suspect's well-being and him getting treatment at a local hospital," Tulsa Police Cpl. Ken Simpson said.

Officers said the clerk wasn't hurt and is not expected to press charges.
