Chris Brown ramps up security following armed robbery

R&B star Chris Brown has reportedly employed a 24-hour security team after armed robbers targeted his home earlier this month (Jul15).

The Kiss Kiss hitmaker's house in California's San Fernando Valley was raided by thieves who made off with money and other belongings after forcing the star's aunt into a closet.

Sources tell TMZ.com that Brown has now stepped up security at the mansion, adding two guards on a 24-hour watch to the perimeter of his home.

The insider suggests that the singer has also decided to limit the number of guests he allows in his home in a bid to tighten security there.
