Murder detectives probe disappearance of crew member, 22, who vanished on a ...

Murder detectives are investigating the disappearance of a crew member on a North Sea ferry 40 years ago amid new fears that he was pushed overboard.

Kevin Dundon, 22, went missing after he was seen washing dishes in the galley of the Townsend Thoresen ferry Viking Viscount on September 21, 1980.

It was thought that Mr Dundon from Clacton-on-Sea, Essex, may have gone into the sea, but a search failed to find his body.

Detectives have now taken new statements from people on board who believe he was a victim of foul play when he vanished 26 miles off Felixstowe, Suffolk.

Andy Guy, the Major Crime Review and Unsolved Case Manager for Norfolk and Suffolk Police, said: 'There seems to be growing support to suggest Kevin's disappearance was not accidental.'

Detectives are now appealing for new witnesses to come forward.

They are convinced that someone among the 86 crew and the 600 passengers on the ferry knows what happened to him.

Mr Dundon had only joined the Viking Viscount three days before disappearing on a return trip to Felixstowe from the Belgian port of Zeebrugge.

The last confirmed sightings of him were at 6.30pm when he left the galley through a door taking him to either the toilets or the deck.

Announcements were made over the public address system asking him to return before searches began on the ship.

Emergency services were informed that Mr Dundon was missing at 10.45pm - two hours after the ferry docked at Felixstowe.

The Viking Viscount left for Zeebrugge again at 11pm and joined three other ships, searching for him near the Galloper lightship until around 1.30am.

Thirty witness statements were taken at the time from people on the ferry, mainly crew members.

It emerged that Mr Dundon had spent time in the staff mess room which was frequented by crew and passengers invited in as guests.

His brothers, Jimmy, Tom and Danny Dundon, have always believed he was a victim of foul play.

Tom Dundon, 63, of Clacton-on-Sea said: 'The police cold case team contacted us again about four or five years to get DNA because the technology for it did not exist at the time.

'We spoke to them again. They re-interviewed everybody who was spoken to at the time and others who were not spoken to.

'They believe now, as we have always done, that he didn't go missing and something happened to him.

'When the boat docked at Felixstowe, a member of the crew went straight to the ship's padre and told him stuff.

'I got a call from the padre that night. He said he had heard some disturbing stuff, but he couldn't tell me what it was.

'This time, the police have been much more pro-active and they have
