Police say two 17-year-olds, a boy and a girl, were slashed aboard a Bx12 MTA bus in Fordham.

Officers responded to the BX12 bus stop at East Fordham Road and Valentine Avenue just before 8 p.m. Wednesday. Citizen app footage shows EMS treating one victim inside the bus shelter.

The boy was slashed in the neck and hand, while the girl suffered a slash wound to the hand, authorities say.

An unknown sharp object was used in the attack.

EMS took the teens to St. Barnabus Hospital, where they are both expected to recover.

Police are looking for a male, last seen wearing a ski mask and all black clothing, who exited the bus and ran away after the attack.
