LITTLE FERRY -- A canoeist on the Hackensack River rescued a man who jumped from a bridge Sunday morning, but officials aren't sure who to congratulate for the save.

Because they don't know his name.

The mystery man in the canoe saw a man jump off the bridge connecting Little Ferry with Ridgefield Park, and then paddled over to rescue him. The canoeist threw the man a rope, then towed him to shore, where first-responders were waiting to give him medical attention.

Then, the rescuer -- who had his dog in the craft -- kept floating on down the river without stopping or telling police his name.

"You can't make this kind of stuff up," Little Ferry Police Chief Ralph Verdi said.

The man who had jumped, a 55-year-old from Garfield, didn't suffer any serious injuries after his suicide attempt at about 8 Sunday morning. He willingly took hold of the rope, and when the canoeist got close enough to shore, he stood up and walked out of the water, Verdi said.

He told police he'd tried the same thing in Paterson. He was taken to Hackensack Medical Center.

"Seems like he got lucky," Verdi said.

Verdi said they're not anticipating any criminal charges. The Route 46 bridge is about 40 feet high, Verdi said, and it's currently undergoing repairs. Bergen County and Ridgefield Park authorities assisted with the rescue.

Note: Due to incorrect information from police, an original version of this story incorrectly stated that the rescuer was kayaking. In fact, according to Little Ferry Police Officer Demetrius Dacres, he was in a canoe.
