Here’s a rule of thumb: Don’t break into LL Cool J’s home.

TMZ reports that a robber tried to steal some of his possessions and when LL heard some noise downstairs around 2 a.m., he went to investigate what was going on.

LL found the intruder because he set off his alarm system. And instead of calling authorities right away, he decided to go face-to-face with the burglar, detaining him until LAPD arrived and giving him a few bruises.
