Investigators want to know what caused a multi-car crash Saturday on the Henry Hudson Parkway.

Six people were hurt, including a police officer; it's unclear if the officer is a member of the New York Police Department.

The accident occurred around 5 a.m. on the parkway near 130th Street in Manhattanville.


There's no word yet on the condition of the victims, or just how badly they may've been hurt.
