Frankie Morris: Divers to join search for missing teenager
Police divers are joining in the search for a missing teenager from Anglesey.
Frantisek "Frankie" Morris, 18, was last seen near the Vaynol Arms in Gwynedd on 2 May, a day after going to a rave at a disused quarry.
The North West Police Underwater Search and Marine Unit tweeted divers will search the Afon Cegin.
Three people have been arrested, one on suspicion of causing death by dangerous driving, North Wales Police said.
A second man and a woman were arrested on suspicion of perverting the course of justice.
One person remains in custody while the others have been released under investigation.
Frankie was last seen on CCTV pushing his bike near the Vaynol Arms.
Officers said they had spoken to a cyclist who was caught on CCTV in the area but he was no longer part of their investigation.
Ch Insp Owain Llewelyn said because of the ongoing investigation the road from Pont Felin, Pentir, heading towards Waen Wen would be closed until further notice.
He appealed for a number of drivers to get in touch.
He said: "A large police presence will remain in the village of Pentir over the next few days whilst we continue to conduct searches.
"I would like to thank the local community for their support and understanding whilst the local roads remain affected by the necessary closures."
North Wales Police also want to talk to three male cyclists seen near the pub at about 13:45 BST that day.
Many volunteers have been involved in the search, using drones and dogs.
Ch Insp Llewelyn said "several useful reports and pieces of information" were being assessed.
"If there is anyone who was at the rave at the disused quarry in Waunfawr on Saturday, please use this link to contact us, anonymously if you prefer," he said.
