The search for a 16-year-old boy who was spotted jumping from a ferry on the Devon and Cornwall border has been called off, the coastguard has said.
Rescue teams wound down their searches just after 2pm on New Year's Day after an extensive hunt for Jordan Cobb, who leaped from the Torpoint ferry into the river Tamar the night before.
The Maritime and Coastguard Agency (MCA) said Brixham coastguard received a mayday distress call from the ferry at 9.15pm on Monday reporting a man overboard near its slipway in Torpoint, Cornwall.
Coastguard rescue teams, a helicopter, police and Ministry of Defence launches, Dartmoor Rescue Group and Plymouth's all-weather and inshore lifeboats were all involved in the search.
Devon and Cornwall police had resumed the search at first light, hoping Jordan had managed to swim ashore.
Nigel Bunker, an MCA station officer, told the BBC there had been no sightings of Jordan since he was captured on the ferry's CCTV going into the water.
The Torpoint ferry, which is pulled across the river Tamar on chains, is a popular way to travel between Devon and Cornwall and was established in 1791.
Speaking to the Guardian, Cobb's martial arts instructor Gareth Russell said he had taken the teenager under his wing a year ago and he had proved talented for his age at Muay Thai boxing.
Russell said the teenager was very popular at the club and that he was still numb from the news that he was missing. "I just hope he managed to get to safety," Russell said. During the early hours of the new year, friends took to social networking sites to pray for his safe return.
Matt Lethbridge tweeted: "Happy new year people but thoughts are with Jordan Cobb. Praying for you my man." He later added: "Going sleep hoping to wake up to good news about Jordan Cobb. Thoughts are with you mate."
Hours before the search was called off, Devon and Cornwall police Chief Inspector Ian Drummond-Smith said: "We are treating Jordan as a high-risk missing person and we are working with the coastguard to try and locate him."
"The river was extensively searched by air and sea for several hours but there remains a possibility that he managed to swim ashore."
Inspector Simon Pawsey at the force's Exeter HQ said police divers also joined the search in the river while the force helicopter was also deployed to use thermal imaging equipment.
Meanwhile, rescue crews in the north of England spent Tuesday morning searching a stretch of Lancashire coastline after a man was swept into the sea in gale-force winds.
The 41-year-old was reported to have been walking his dog in Blackpool with another man when both ended up in the water shortly after midnight.
The second man was able to get out and raise the alarm.
A search was carried out overnight by RNLI and coastguard crews from Blackpool and Lytham St Annes, assisted by the Lancashire police helicopter and the search and rescue helicopter from RAF Valley on Anglesey. Stuart Atkinson, watch manager at Crosby coastguard station, said: "We received a call at 12.13am from Lancashire police reporting that a male was in the water near the South Pier at Blackpool.
"A second male had been in the water but managed to get to safety and raise the alarm.
"We believe, but it's not confirmed, that they were walking their dogs. We do believe a life ring was thrown to him and a football. We have located the football but not the life ring."
