TMZ is reporting that a construction worker committed suicide while at Mel Gibson's Malibu home today tells a law enforcement source.

It happened at Mel's Agoura Hills home -- near Malibu. The construction worker was 47-years-old. It was reported that he hanged himself.

The Sheriff's substation in Lost Hills took the call at 8:07 AM -- that's the same station where Mel was taken after his DUI arrest in 2006.

Mel was not at the house when the body was discovered. A law enforcement source says no one from Gibson's family was living at the house -- it is currently under heavy construction.

Okay, stop construction. Find new home!!! Creepy!
