Details are still surfacing, but New York State Parks Police arrested rapper Big Sean during the Wiz Khalifa show at Artpark on Thursday night.

Big Sean, one of the night’s opening acts, was arrested along with another man on charges of forcible touching, sexual assault and unlawful imprisonment after an incident with a female.

Police huddled with a group of teenage girls while Khalifa was on stage, trying to find one member that had gone missing. Police were passing a cell phone from from one of the teens, reading a text message.

According to a release from the State Parks Police, an investigation started at 9:50 p.m. after a call of a complaint from a female who said she was sexually assaulted.

Two men, Willie Hansbro and Sean Anderson, both from Detroit, were charged with forcible touching, second-degree unlawful imprisonment and third-degree sex abuse.

The two men were issued appearance tickets and were released on $500 bail.

Police gathered near the entrance with a handful of teenage girls, many of whom were crying.

This after a sellout crowd largely comprised of suburban teens was relatively tame during the sold out show, with a smattering of arrests for possession of marijuana, and a few minor incidents in which youngsters tried to climb the side walls to get in.

Local police enforcement were worried possible episodes surrounding the Khalifa show. Artpark beefed up security, putting 80 security guards on the show, adding a drug-sniffing dog on the premises, and using wands to check for weapons.

Anderson is a Detroit native and was supposed to be part of a homecoming show as part of the Rolling Papers tour that’s scheduled to appear in the Detroit suburb of Pontiac tonight.
