Ohio police are looking for a man who used a two-by-four piece of wood to rob at least three patrons at a Dayton restaurant Thursday night.

The man took several cell phones during the robbery that occurred in the outdoor eating area of the restaurant at about 9:30 p.m., Dayton police said. No one was injured.

Police brought in a K-9 unit as several officers searched the neighborhood for the assailant.

Anyone with information about the incident or the suspect is asked to call 937-333-COPS, police said.
