LAPD present to keep the law at Rapper Meek Mill party for BET Awards to

SHUTTIN' IT DOWNTMZ.com

Meek Mill's party was overrun Friday night by both clubgoers and cops, who were determined to keep the peace in Hollywood during the BET Awards weekend.

The rapper hosted a big party at Playhouse Hollywood, which was packed to capacity just after midnight.   A slew of cops showed up -- on the ground and in the air -- to control the crowd and prevent a repeat of last year's violence during pre-show parties.

A eyewitness says YG was rejected after he refused a pat-down.

All was calm and it looks like only one or 2 people were busted for disorderly conduct.

One down, one to go.
