Dyfed-Powys Police say there have been no confirmed sightings of Owain since 10 March last year. They say officers have acted upon all pieces of information or possible sightings they have received but Owain remains a missing person.
This has been an incredibly difficult time for his family, and after a year they are once again appealing for help and asking that anyone who may have any information relating to his whereabouts or his disappearance contact the police.
Dyfed-Powys Police officers will be handing out leaflets in the Mwnt and Cardigan Road areas of Cardigan today as part of the renewed appeal.
