Chris Brown: Another Trespasser Arrested at Home

Chris Brown had another unwanted guest on his property who made her way in, refused to leave and ended up in cuffs ... TMZ has learned.

Law enforcement sources tell TMZ, it happened at 5 PM Tuesday at Chris' Woodland Hills mansion ... the same place where home invaders held his aunt at gunpoint and stole $50k.

This time around we're told a 27-year-old woman waited at the electric gate in front until someone left, and then drove onto the property.

Security ordered her to leave but she refused, and cops were called. They arrested her for criminal trespass.

Chris was at home but never came out.
