JOPPA, Md. (AP) — One teen shot another during a dispute in a Maryland high school bathroom Friday in what authorities called an isolated incident.

The victim, a 15-year-old student at Joppatowne High School, was in serious condition after being airlifted to a hospital, the Harford County Public Schools said in a news release, citing information it received from the county sheriff’s department.

A 16-year-old student whom police identified as the shooter fled shortly afterward but was caught minutes later nearby, according to the news release. Officials said no information would be released immediately about the weapon, which had not been recovered.

The state’s attorney has said the suspect will be charged, the release said, citing Harford County Sheriff Jeff Gahler.

Shortly after the shooting, the sheriff’s office asked people to avoid the area, but emphasized that the confrontation was an “isolated incident, not an active shooter.” A parent-student reunification center was established at a nearby church. More than 100 personnel responded to the high school about 20 miles (32 kilometers) northeast of Baltimore, Gahler said.
