Authorities say a truck has fallen through the upper level of a parking garage in northern New Jersey.

But no injuries have been reported.

The accident happened shortly before noon Wednesday at the parking facility on Tonnelle Avenue in North Bergen. It�s not yet known what caused the collapse, but it didn�t appear that any other vehicles had been damaged.

Video showed a large hole where the collapse occurred. The front end of the truck was seen in the hole, which had been cordoned off.

The collapse remains under investigation.
