PHILADELPHIA (WPVI) -- A lockdown that was put in place at the Frances E. Willard Elementary School in Philadelphia has been lifted.
The lockdown was put in place around 12:30 p.m. Monday.
According to police, the principal called 911 to say a parent was coming to pick up a child while armed with a gun.
The situation apparently stemmed from a custody dispute, police say.
The lockdown was lifted shortly before 1:20 p.m. without incident, police say.
