Two lifeboats were launched in Tenby's North Bay late on Sunday evening in the search for a missing person.
Tenby's RNLI inshore lifeboat was launched just before 9pm as concern grows for 21-year-old Billy Miller, who was reported missing on the weekend.
Mr Miller, from Fishguard, was last seen at 11.30pm on Saturday evening in Warren Street in the Pembrokeshire seaside town.
A second lifeboat was launched into the bay on Sunday at 9.15pm while HM Coastguard Tenby and St Govans Coastguard Rescue Teams, along with Dyfed Powys Police, searched the shoreline and cliffs above.
Both lifeboats searched the harbour and the shoreline as well as all the coves and beaches between Telpyn Point and Castle Beach.
With the search area exhausted and with nothing found, both boats were stood down and returned to station at 10.35pm.
A spokesman for Dyfed Powys Police said: "We are appealing for information to find 21-year-old Billy Miller from Fishguard who has been reported missing.
"Billy was last seen in the vicinity of Warren Street, Tenby at approximately 11.30pm on Saturday June, 20.
"He is described as a white male, approximately five foot eight inches tall and of a slim build with short back and sides brown hair. He was last seen wearing blue tight fitting ripped jeans, an over-sized grey sweatshirt and a navy blue baseball cap with a red logo."
Anyone who has seen Billy, or anyone who has information on his whereabouts, is asked to contact police by phoning 101.
