HOUSTON -

A man who crashed a stolen van into a southeast Houston bayou is still missing.

Witnesses say they spotted him on top of the van Tuesday night. Witnesses threw ropes at him but he refused. Firefighters reportedly saw him get swept away by the water.

Police say the van was stolen from a contractor at the University of Houston.

Crews pulled it out of the water, but the man was gone.

Drive teams say the water is too dangerous to search right now.
