(ABC 6 News) -- It was a standoff that lasted several hours, shutting down major roads near a small north Iowa community with more than a half dozen law enforcement agencies responding before it was all over.
It all started early this afternoon when authorities in Lake Mills, Iowa, got a rescue call for 21-year-old Matthew Davis who had intentionally hurt himself and needed help.
When an ambulance and police officers arrived at the rural home on the eastern edge of the city, Davis allegedly opened fire with a shotgun.
Officers returned fire but no one was hurt in the exchange.
Police say that's when the man retreated inside the home and police set up a perimeter, blocking off roadways for miles around as a way to try and keep residents safe.
After several hours the man surrendered to police without any further violence.
But this is not the first time police have dealt with this particular suspect.
"He's needed some help before, he's just depressed is the main thing,” said Worth County Sheriff Jay Langenbau. “So we've had contact with this individual before and I know that friends and family are always trying to help him out, and we're trying to help him out too."
Langenbau said the suspect had visible wounds on his arms when he exited the building. Officials say Davis was taken to Mercy Hospital North Iowa for self-inflicted knife wounds. He was later released and is being held at Worth County Jail on attempted murder charges.
