Deputies are looking for help identifying a man they say pummeled a Circle K clerk days after being refused a courtesy water cup.

Just after 7 p.m. Sept. 10, the clerk was standing outside the Circle K at 5818 South Palo Verde Rd. when he was attacked, Deputy Cody Gress said in a news release Thursday.

The man punched the clerk several times in the face before being scared off by a friend of the clerk who saw the beating.

The clerk told deputies the man was angry he did not get a courtesy cup of water several days earlier, Gress said.

The attacker is believed to be in his 30s, with short brown hair and a goatee. He about 5 feet, 10 inches tall and is of a medium build.

Anyone with information is asked to call 88-CRIME, the anonymous tipster line.
