A "distressed man" sparked an emergency rescue after he was discovered waist high in the sea at Blackpool, say police.
The man was spotted by a member of the public who heroically ran into the sea near Central Pier, pulling the man to safety.
Police say coastguard rescue teams were also scrambled to the emergency and helped escort the man from the beach.
A spokesman for the Coastguard said: "We were alerted by a member of the public at around 9.15pm on Tuesday, who reported concerns for an adult male who was seen entering the water.
"The member of the public then entered the water and pulled him out.
"He was in for less than 10 minutes.
"We sent the inshore lifeboat from Blackpool and the Lytham and St Annes Coastguard Rescue Team to assist.
"The man was handed into the care of paramedics."
A spokesman for the Ambulance Service confirmed that they took a man to Blackpool Victoria Hospital for assessment.
The Coastguard recorded its busiest May on record with 31 jobs last month, and are on red alert for another action-packed summer.
Fleetwood Coastguard said it was called out to 109 incidents last year. They included 41 reports of somebody in the water, including children playing on a blow-up killer whale and people being cut off by the incoming tide. Some 35 missing people – ‘sometimes vulnerable’ – incidents were also logged.
