Police investigating a mass shooting at an Ohio music festival detained an 18-year-old suspect for questioning, according to his father who spoke with media on Monday.

The teenager was taken into custody in connection with Saturday’s shooting at Old West End Fest in Toledo, where 12 people were wounded, according to local reports.

Authorities were seen carrying out a search warrant Monday afternoon at a home on Marmion near Nebraska in Toledo as part of the investigation.

Forensic teams set up a blue tent outside the property, where the teen’s father confirmed that his son lived.

Police have not announced any official charges and have not released details about the search warrant.

Investigators previously said the shooting began after a confrontation involving two separate shooters.
