Firefighters were called to Brighouse last night to reports of men who had jumped into the canal.
Two men had jumped in at about 12.20am this morning (Saturday) in Briggate.
By the time Brighouse fire crew arrived, the men had managed to get out of the water.
Another friend is believed to have jumped in to reach them and a fourth helped drag them in from the bank.
It is understood the pair were only in the water for a matter of seconds but they were checked over by paramedics at the scene.
