William Allen High School, Raub Middle School, and Union Terrace Elementary all were placed on lockdown as a precaution after officers received a report of a person with a weapon on Linden Street in the West Park neighborhood around 8:50 a.m., Allentown police said.
Officers eventually found a juvenile in the area with a loaded semi-automatic handgun, they said. The minor was subsequently arrested.
The lockdowns were lifted just after noon, police said.
Anyone with information on the incident is asked to contact the Allentown Police Criminal Investigation division at 610-437-7721 or make an anonymous tip through the Allentown Police Tip411 app.
