Actor Charlie Sheen has paid tribute to old pal Chris Penn, who was found dead in his Los Angeles apartment on Tuesday (24JAN06) - calling him the "best friend a guy could ever hope for".

Sheen and his sibling Emilio Estevez grew up with Penn and his brother SEAN, and his father Martin Sheen was one of the first to arrive on the scene of the mystery death to comfort the RESERVOIR DOGS star's mother.

In a statement from the PLATOON star, Sheen also calls his pal "a good and decent man," adding, "I loved him."
