LL Cool J came face-to-face with a burglary suspect in his home, and took the guy down with his own hands early this morning … TMZ has learned.

Reports TMZ:

According to law enforcement sources … the suspect entered LL’s Los Angeles area house around 2AM, but unfortunately for him the actor/rapper/badass was home.

We’re told LL heard some commotion downstairs, went to check it out … and found the intruder.

Sources say the intruder had tripped LL’s alarm system, but the “NCIS Los Angeles” star — who is a physical beast — decided to go hand-to-hand combat on the dude … and managed to detain him until LAPD arrived a few minutes later to make the arrest.

We’re told LL is okay, but the suspect — who will be booked for burglary — suffered a few bruises.

Out of all the rappers to try to break in their homes, this stupid burglar picks LL Cool J. LL Cool J prides him self on being in shape.... At 44 he is in better shape then most 22 year old men. What was this guy thinking ? He got exactly what he deserved jail and being knocked out.
