MOON TOWNSHIP (KDKA) -- Two schools in Moon Township were placed on lockdown Monday.
Around 2:30 p.m., reports began to come in that Moon Area High School was under lockdown.
Officials say a mother was arriving at the high school to pick up her child, when she noticed a man was tailgating her.
Eventually, she confronted the driver.
"She walked back, got out of her vehicle and said 'what's your problem,' explained Moon Township Police Chief Leo McCarthy. "And he pulled a handgun out, pointed it out the window right at her and he told her basically to get away."
Police were concerned the man drove further onto the school's campus, and placed the high school and middle school under lockdown. Officers later escorted students to their buses as a precaution.
Authorities are working to find the alleged gunman. He is described as a white man in his late-teens to early-20s with dark, curly hair and a scruffy beard. He was wearing a white t-shirt and driving a black SUV or Crossover.
Chief McCarthy says the whole incident really shook the mom up.
"She was extremely traumatized regarding this," he said. "If you're not used to looking at guns, you just see that barrel. It looks real big coming right at you."
