A major search was launched after reports of a man missing out at sea off Blackpool pier.
Police, a coastguard helicopter, lifeboats, and paramedics were at the scene after being called out to the incident on Saturday morning.
HM Coastguard was alerted by a 999 call reporting that a man had been seen entering the sea near the North Pier and the search has been underway since 10am, Lancashire Live reports.
The search, which has been co-ordinated by Holyhead Coastguard, in North Wales, has now been suspended for the rest of the day due to
fading light.
A Holyhead Coastguard spokesman said: "We received a call at around 9.30am today reporting that a male had entered the water at North Pier
in Blackpool."
