The Buffalo Swat Team surrounded a house on Koester Street at about 6 p.m. there were reports of shots fired inside the home.
"We quickly surrounded the house and started negotiating...negotiations broke down very quickly," said Swat Commander Mark Maraschiello.
Police are not yet releasing the 54-year-old man's name but say the situation quickly took a turn for the worse.
"He became threatening, he was just going back and forth out one door out the other. We didn't know whether he had weapons inside or not. We couldn't confirm if there were shots fired or not," said Maraschiello.
Nor did the police know if anyone else was inside. The man's dog was outside, seemingly confused about all of the chaos.
Once the swat team had a clear view of the man just inside the door they used rubber bullets to incapacitate him. He was hit twice in the stomach.
"It's like getting hit with a major league fastball," said Maraschiello.
The man was taken out of the home on a stretcher; police say he was incoherent and drunk.
Investigators found firecrackers inside the man's home, but aren't sure if those were the sounds neighbors reported hearing. The man was taken to ECMC for a psychiatric evaluation. No charges have been filed against him yet.
