Lifeboat crews say a man is lucky to be alive after being rescued from rocks off Redcar.
A police helicopter, the coastguard and an RNLI shore party were called out early on Friday after the 37-year-old dialled 999 from his mobile phone.
He was located using searchlights and treated at the town's lifeboat station before being handed over to police.
The man narrowly avoided drowning as the tide would soon have submerged the rocks, according to the RNLI.
Dave Cocks, from Redcar RNLI, said: "The man is very lucky to be alive. The tide was on the way in.
"Where he was found would have been submerged within another hour or two and the outcome could have been very different if he hadn't been found so quickly."
