SPRING LAKE PARK, Minn. (AP) — No one has been arrested following a shooting that left one person dead and seven others injured outside a Thai restaurant in suburban Minneapolis, sheriff’s officials said Monday.

An altercation between two groups of people in the parking lot of Dala Thai Restaurant and Banquet Hall in the City of Spring Lake Park culminated in the shooting just after midnight Sunday, according to Anoka County Sheriff’s Cmdr. Wayne Heath.

It was not yet known whether more than one person fired a gun, only that multiple shots were fired, Heath said. The suspect or suspects are not among the victims, according to sheriff’s officials. No weapon was recovered, the commander said.

The man who died was identified as 19-year-old Chai Yang, of St. Paul. Injuries to the seven others, ranging in age from 19 to 38, are not considered life threatening, sheriff’s officials said.

Cambodian-American rapper $tupid Young, who attended a party at Dala Thai on Saturday night, posted a message on Instagram after the shooting: “Prayers to the ones who got hurt. I appreciate you.”

Spring Lake Park, a city of about 6,400, is about 12 miles (19 kilometers) north of Minneapolis.
