Parkway West reopens after large police presence; 1 in custody

A person is in custody and the Parkway West is back open after a large police presence shut down the highway on Thursday afternoon. 

Both directions of the Parkway West between the I-79 and Route 121/Greentree/Mt. Lebanon interchanges were shut down on Thursday due to police activity, PennDOT said. 

Westbound, or outbound, reopened first, while eastbound followed shortly before 4 p.m. The police presence also shut down ramps to the Parkway West, PennDOT said. 

During the closure, drivers were encouraged to use alternate routes. 

Police provided few details on Thursday, but around 3:30 p.m., troopers said that a person was taken into custody. There's no threat to the public, troopers said. Police didn't say why they were looking for that person in the first place. 

While the Parkway has since reopened, police warned that there will be residual traffic for the remainder of the afternoon.

The Keystone Oaks School District said the police activity near Wilson Park prompted a lockdown of Fred L. Aiken Elementary School, which is located along Greentree Road, around 1:45 p.m. The lockdown was lifted around 3:40 p.m., delaying dismissal by about 20 minutes, the district said. 

Authorities didn't immediately release any other details.
