NBC10 was live on the scene when the lockdown was lifted on Overbrook High School after a teacher thought she heard a gunshot. No evidence of a shooting was found, police said.
A West Philadelphia high school was put on lockdown for about an hour Wednesday morning after a teacher reported hearing a gunshot and a student possibly saw a gunman run out of the building, Philadelphia police said.
Officers searched Overbrook High School after the reports came in around 9:20 a.m. but they found no evidence of a shooting, police said.
A teacher claimed to hear a gunshot and the student claimed to see a classmate running from the school on Lancaster Avenue with a firearm, police said.
"She heard a loud bang, and that's how it was described to me," police Capt. John Stanford said.
Police set up a staging area near the school as detectives searched for whether gunshots were actually fired.
"One of the key things is making sure we get the accurate information," Stanford said.
The lockdown was lifted around 10:20 a.m. after police found no ballistics evidence of gunfire.
