A Royal Navy submariner from Co Antrim who claimed security and safety procedures around the Trident nuclear programme mean it could be "infiltrated by a terrorist" has said he will hand himself in to police.
Military and civilian police are working to locate Able Seaman William McNeilly (25) who went absent without leave last week after producing an 18-page report containing a series of allegations about the Trident submarines based at Faslane on the Clyde.
The Newtownabbey man's report alleged 30 safety and security flaws on the submarines, describing it as a "disaster waiting to happen''.
The Royal Navy said the Trident submarine fleet operated "under the most stringent safety regime".
A post on a Facebook profile apparently belonging to Mr McNeilly said he had "moved between countries, changed location almost every day", but now "lacks the resources to remain undetected".
"I will be handing myself into the police today," it said yesterday, although there were no reports to suggest he had last night.
In his report, which was published online and also sent to newspapers and journalists, Mr McNeilly said he is an engineering technician submariner who was on patrol with the Trident submarine HMS Victorious this year.
He claimed there are fire risks and leaks on board and that security checks are rarely carried out on personnel and contractors working on the submarines when they are docked at Faslane.
