Emergency services were scrambled to help rescue a man from the sea off Roker Pier.
Sunderland RNLI, along with the police, coastguard and ambulance crews, were called to Roker Pier at 8.55pm yesterday.
A man was reported to be in trouble in the water on the south side of the pier.
Sunderland’s ‘D Class’ lifeboat was launched, but the man managed to make his own way out of the water.
He was taken to hospital with a head injury.
Gav Hughes, crewman at Sunderland RNLI, said: “Although we do not know how the person entered the water or gained his injuries, he was thought to have been fishing on the pier.
“Nationally, it is recognised that a lot of people who end up in trouble never intended to enter the water.
“That is why the RNLI is encouraging people to ‘Respect the Water’, in the hope fewer people will drown around the UK’s coast.”
