Philadelphia police Sunday were continuing to investigate the circumstances leading to an 11-year-old boy arriving at Children's Hospital Saturday with a gunshot wound to his left leg.

While the unidentified boy told police he had found a gun at Vare Recreation Center in South Philadelphia and that it discharged when he picked it up, surveillance cameras at the center did not reveal an incident there, police said.

But at the youth's residence in the 1500 block of South 26th st., police reported finding blood and bloodied clothes in several rooms. "There is also a bucket of water and blood soaked rags and socks, which leads one to believe that someone was attempting to clean up the scene," the police department statement said.

"We're fairly confident it didn't happen in the rec center" police Lt. Ray Evers said. "There is a good amount of blood to indicate something might have happened in the house."

The youth's condition has been reported as stable.
