Michigan ? Gunfire erupted during halftime at a middle school football game Wednesday afternoon in Saginaw, wounding two adults and two teenagers, police said.

The four were taken to hospitals for treatment, said police Lt. Brian Lipe.

A 16-year-old boy was shot in the neck, Detective Sgt. Brent Vanderhaar said, but he said he had no information on his or the other victims’ conditions. He also would not say whether the boy had been targeted by the shooter but did say the other victims apparently were innocent bystanders.

No arrests had been made, but police had one person in custody being questioned as a “person of interest,” Vanderhaar said.

The injured teenagers were not students at South Middle School, where the shootings took place about 5:15 p.m. The other victims were an adult male and an adult female, Vanderhaar said. He declined to provide more details.

About 100 people were attending the game when the shooting erupted a short distance from the school’s football field, where the team was playing Central Middle School, Vanderhaar said.
