CUMBERLAND COUNTY, Pa. (WHTM) – A police chase involving two crashes sent two Pennsylvania State Troopers to the hospital and closed a section of US 11 in Cumberland County for more than three hours on Friday.

According to State Police, a car that was believed to have been involved in a retail theft in Carlisle was seen speeding on I-81 northbound around 10:45 a.m.  The car was eventually stopped on Route 581 near the Carlisle Pike, where troopers say three males got out of the car and ran. Two were arrested minutes later, but police say the third stole another vehicle, which crashed a short time later near Silver Spring Road and the Carlisle Pike. The male in that car was also taken into custody.

Cumberland Valley School District officials say the search for those males led them to put three schools in a precautionary lockout, meaning no one was allowed to enter or exit the buildings.  The lockout was lifted around 11:45 a.m.

State Police say two troopers from the Carlisle barracks were responding to the incident when their vehicle collided with a tractor-trailer, which was making a U-turn on the Carlisle Pike at Dapp Lane, close to Cumberland Valley High School.  Officials say the troopers were taken to Holy Spirit Hospital with serious injuries. This crash closed the Carlisle Pike for several hours.

Students at Cumberland Valley High School were dismissed in a staggered schedule to minimize traffic due to the accident starting at 2:45 p.m. The school says pickups can begin at 2:45 p.m. and that parents should anticipate delays in drop-offs.
