NEWARK, Del. (CBS) — Officials say they have signed warrants for the arrest of a 57-year-old man in connection with a shooting involving police that took place in Delaware and on Tuesday afternoon.

The incident on Lawrence Avenue in Newark prompted a massive response by law enforcement.

Authorities say David P. Ashby, who lives on Franklin Street made concerning remarks about his welfare, so New Castle County police were sent there to check up on him.

“As the officers arrived on scene, gunshots could be heard from inside,” said New Castle County Police Master Cpl. Michael Eckerd.

Authorities are unclear at this time whether the shots were directed at police, but the initial officers backed away from the home and called for backup.

Within minutes, more than 50 officers were by their side.

A standoff ensued between police and the suspect and eventually he surrendered. He was taken from the house in handcuffs and on a stretcher.

“The subject was transported to an area hospital for evaluation. I believe he was being evaluated for a self-inflicted wound. I believe it was a knife wound,” said Eckerd.

At this time, authorities are not releasing the name of the suspected shooter.

He has not been charged at this time and the investigation is ongoing.

The standoff closed Kirkwood Highway between Pike Creek and Harmony Roads for a period of time.
