Cops are sending patrol cars to Justin Bieber's house numerous times a day to make sure people are letting him live in peace ... because they say, "He's not an animal in a zoo." The Sandy Springs Police Dept. is responsible for patrolling the area where Bieber is living.
A Captain for the PD tells TMZ, they're aware Bieber is a big celeb who attracts lots of fans, especially young girls. The Captain says they are now putting cops on special patrol, specifically driving past the home multiple times every day and night ... to make sure people aren't loitering and trespassing.
