Ann Arbor police officers were called to Pioneer High School Thursday evening after an attendee at the Choral Cavalcade choir concert was spotted openly carrying a firearm.

Sgt. Shane Dennis said officers responded to the school at approximately 7:30 p.m. to investigate the incident.

"The individual has a concealed pistol license and you cannot carry a concealed weapon at a school, but you can open carry in a school [with that license]," Dennis said.

"It might sound like that doesn't make any sense, but that's the law."

Background:

According to a Facebook post from Ann Arbor musician Brian DiBlassio, Pioneer director of choirs Steven Lorenz spotted the man with the gun in the audience and made the initial call to the police.

Other parents and students who attended the event expressed concern via Facebook and other media.
