A parent attending a high school volleyball tournament at Gladstone High School on Saturday left his gun in a bathroom, and it was later seized by police, the school district said this week.

A visiting team's coach found the handgun on top of a toilet paper dispenser in a bathroom near the gym, picked it up, took it out of the school and called police, Gladstone School District Superintendent Bob Stewart said in an email to parents. The coach later told the tournament director about the discovery.

No one was injured. Stewart said the district is grateful for the coach's "quick and appropriate action to protect students."

A parent later told a building supervisor that he'd left his gun in a bathroom stall and forgot to pick it up, the statement said. He had a concealed weapons permit.
