A truck carrying about 100 monkeys was involved in a crash on Friday in Pennsylvania.
State police said as authorities searched for at least three of the monkeys that appeared to have escaped the vehicle.
The truck carrying the animals crashed with a dump truck in the afternoon in Montour County, Pennsylvania State Police Trooper Andrea Pelachick told reporters.
The truck had been on its way to a lab, Pelachick added.
Authorities have asked residents who might see the monkeys to call state police.
It was unclear if any people or animals were injured in the crash.
