State police are investigating after a 90-minute standoff with police in Plymouth ended with a man being flown to the hospital.

Officers were called out to a wooded area on King Road north of 9-A Road because a man was threatening suicide.

After talking with him for an hour and a half, they tried to intervene.

The man shot himself during the struggle with police.

He was airlifted to a South Bend hospital, and his condition isn't known.

Detectives are now looking into the circumstances surrounding the shooting.
