Authorities in Philadelphia say a minivan that crashed through a fence and plunged into the Delaware River has been pulled from the water, and they're searching for anyone who may have been inside.

Police say they do not know how many people may have been in the van, which was recovered around 5 a.m. Sunday.

A witness tells WPVI-TV (http://6abc.cm/1W6SqBV ) he saw a vehicle speeding toward the river about 3 a.m. and then heard a crash and a splash. He says he ran toward the river and saw that the vehicle had torn through a fence and disappeared in the water. He called 911.

He says no one came to the surface while he was there.
