Several cadets from the U.S. Military Academy at West Point in New York were injured when their van crashed in Pennsylvania after a boxing competition, officials said Friday.

State police said the van carrying nine cadets flipped after swerving to miss a car that had illegally used a cross-over path for emergency vehicles. The crash happened around 8 p.m. Thursday on westbound Interstate 80 in Sugarloaf Township, Luzerne County.

The nine cadets in the van were members of the boxing team leaving the East Regional Championship competition at Penn State, the West Point public affairs office said in a written statement.

The van's driver wasn't hurt. West Point said Friday that seven of the eight injured passengers were treated and released from local hospitals by late Friday morning, with the eighth cadet expected to be released soon thereafter, West Point said.

The accident remains under investigation. The other driver left the scene, state police said.

Authorities urged anyone with information on the identity of the other driver, or the location of the other vehicle that used the cross-over road, to contact state police.
