SAN CARLOS -- Two security guards at a home improvement store were clubbed Sunday when they confronted two men who tried to steal about $2,000 in power tools, police said.

The suspects hit the guards with a "small wooden bat" in the parking lot of the Home Depot store on Old County Road around 6 p.m. Sunday. Neither guard was seriously hurt and the would-be thieves got away, but without the tools, said Sheriff's Deputy Rebecca Rosenblatt.

Store security guards began keeping an eye one of the suspects, a Hispanic man in 20s who appeared to weigh over 300 pounds, because he loaded a cart with about $2,000 worth of power tools. The guards found that suspicious and so were watching when he rolled the cart into the parking lot without paying, Rosenblatt said.

The guards confronted the 300-pound man as he pushed the cart toward a getaway vehicle, which police described as a newer model Honda Accord with tinted windows and large rear spoiler. When the guards told the suspects to stop a fight started.

The suspect in the car was a white man in his mid to late 20s with blonde hair who was about 6 feet tall and appeared to weigh about 185 pounds, police said. Both suspects wore short sleeve shirts and blue jeans.
