Man falls into Humber River

Rescuers will resume their search on Thursday morning for a man who fell into the Humber River.

A rescue operation was called off late Wednesday night when darkness fell.

It began in the late afternoon near Lawrence Avenue after the man went into the river and disappeared.

Police say the man's dog went into the river and the man jumped into the water to save it.

The dog managed to get out of the water, but the man has not been found.

The water level is high and the water is moving faster than normal due to the recent heavy rainfall.
