Authorities said London police said a rescue vessel from the Royal National Lifeboat Institution were called to the London bridge around 11 p.m. Wednesday on a report of a man threatening to jump from the bridge, the Daily Telegraph reported Monday.
The RNLI lifeboat arrived in the area and discovered a second man having difficulty remaining on the surface of the water due to being weighed down by heavy clothing. He was pulled from the water.
Lifeboat crew members said the man offered no identifying information other than his age, 33, and the rescuers found he was suffering from hypothermia and was confused about how he had come to be in the water.
"Although he seemed alert and spoke to the crew, he was apologetic and wasn't sure who he was or how he came to be in the river," lifeboat crew member Toni Scarr said. "There were no other boats in the area at the time and I don't think anyone was actually aware he was in the water. Chances are if it hadn't been for the lifeboat crew launching to the original incident -- he would never have been spotted and would have drowned."
Scarr said the man's confusion may have been brought on by the hypothermia.
Meanwhile, police were able to convince the man on the bridge not to jump and he was helped back to safety.
