State police are investigating an early-morning shooting on I-95 that left one person wounded and partially shut down traffic for several hours.

The shooting occurred around 7 a.m. Sunday, in the northbound lanes of the highway approaching the Cottman Avenue exit, a Pennsylvania State Police spokesperson said.

The victim sustained a non-life-threatening injury to the shoulder. The suspected shooter was taken into custody, police said.

Portions of I-95 northbound remained closed until just before noon Sunday, the spokesperson said, while investigators gathered evidence from the crime scene.

Police have yet to release a motive or any charges in the incident. The identities of the victim and alleged shooter were not immediately available.
