PORTLAND (WGME) -- Police have confirmed the show at the State Theatre Sunday night was cut short because a 29-year-old man was stabbed.
The whole place was evacuated and now police are looking for the man who they say is responsible.
Jeremy Daros says the band "Dirty Heads" put on a great show at the State Theatre Sunday night.
He gave CBS 13 a video of the group in action.
He says the crowd was into it and the show seemed to be wrapping up.
“It was almost a low key happy mood as you see at the end of a lot of concerts; nothing was out of the ordinary,” Daros said.
Behind the scenes, Portland police say they got a call from the State Theater staff, that someone was stabbed.
Once they got to the theatre, police say everyone agreed to end the show early and start evacuating the theatre, forcing nearly 2,000 people inside to leave.
“When we started to file out; noticed a lot of police officers; some EMT people around,” Daros said. “There was a person who appeared to be injured; they were putting him on a stretcher.”
Police say before the stabbing, there was a fight inside between the suspect and several other people.
Still, Daros says no one panicked and police were good with the crowd and keeping order.
“As far as I could tell, the crowd didn't know what was happening,” Daros said.
The State Theatre has a "No Weapons Allowed" policy, boldly displayed at the entrance.
No one at the venue got back to us Monday, and it's unclear what was used to cause the victim's injury.
Daros says security was tight.
“Security was patting everyone down when we walked in,” Daros said. “It's surprising that somebody would have been able to have an object that would be able to do damage to someone not caught by security up front.”
Police say the victim was taken to the hospital with injuries that are not life-threatening.
The suspect is described as a white man, 28 to 33 years old.
He's 5’8” to 5’11” with an average build, clean shaven, and short black hair.
