THREE people released under investigation in relation to the disappearance of Frantisek “Frankie” Morris have now been eliminated from the inquiry.

It has been four weeks since Frankie was last seen. He was last seen walking in Pentir, near Bangor in Gwynedd, at about 1.20pm on Sunday, May 2.

Lee Boycott, detective chief inspector, said: “It is now four weeks since Frankie was last seen. His family are understandably deeply distressed and I continue to appeal to anyone who has any information whatsoever to speak to us.

"However small you might think the information is it might be the piece we’re looking for, please make that call for Frankie and his family.”

As the investigation to find Frankie, who is from Llandegfan, Anglesey, continues, officers said they are grateful for the information received so far.

The 18-year-old had attended a 'rave' in Waunfawr, near Snowdonia National Park, the night before his disappearance.

North Wales Police released an image of Mr Morris walking past the Vaynol Arms pub in Pentir at around the time he was last seen.

Mountain rescue teams, divers among a number of other volunteers have all being involved in the search.

Anyone with information that might help police are asked to contact the investigation team.
