Four adults were injured during a shooting Wednesday night in Detroit. 

All four are recovering at local hospitals from injuries that Detroit Police Department described as "non life-threatening." 

The altercation started during a barbecue in the 14300 block of Mettetal Street. All of them were attending the barbecue and knew each other, policer Captain Matthew Bray said. 

A suspect was taken into custody shortly afterwards. 

The incident remains under investigation.
