Ravers urged to help locate teenager who has been missing for almost two weeks

Detectives searching for a missing teenager have appealed for anyone who attended a rave in a disused quarry to come forward.

Frantisek Morris, who is known as Frankie, was last seen walking in Pentir, near Bangor in Gwynedd, North Wales, at about 1.20pm on Sunday May 2.

The 18-year-old had attended a party 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.

Detective Chief Inspector Lee Boycott said: “We are really grateful to the community for the hundreds of phone calls and online reports we have received in response to our previous appeals. As a result we are examining numerous different lines of inquiry.

“I would like to appeal directly to anyone who attended a rave in the disused quarry above Waunfawr on Saturday May 1 who hasn’t already come forward to do so.

“I understand people may be reluctant due to the fact that the rave was not an organised event, but I would like to reassure you that we are only concerned in piecing together as much information about Frankie’s movements as possible.”

He added that residents in Pentir will have noticed an increased police presence in the area over recent days, which will continue.

“If you were in the area on Sunday May 2 and may have seen Frankie please get in touch, especially if you have dashcam or any other form of video,” Detective Boycott said.

“Finally, I would ask residents in Pentir and the surrounding areas to check any sheds or outbuildings on their land, and contact us if you find anything out of the ordinary.”

Those who attended the rave and have photos, video or have any information are being urged to visit mipp.police.uk - where visitors can pass on information or upload images anonymously.
