SCORES of late night revellers have been interviewed by police piecing together the last hours of father-of-four David Griffiths.

The 39-year-old's crushed body was found by a worker in a heap of rubbish being sorted and graded at a recycling plant in Middlesbrough's Dockside Road, two weeks ago yesterday.

Police think the unemployed construction worker may have climbed into a skip to sleep off the effects of a long drinking session, only to be compacted with the rubbish he was lying in, by a specialist wagon before being transported to the grading shed at the premises of Teesside Waste Management.

Nevertheless, detectives are still treating his death as "suspicious" and teams of officers have questioned late night visitors to Middlesbrough town centre and drinkers at the Zetland Street pubs, Deniros and Isaac Wilson, visited by heavily-tattooed Mr Griffiths.

Detective Superintendent Mark Braithwaite, the man leading the investigation, said of the six-hour operation which finished in the early hours of yesterday: "We had a good response to our questionnaires.

"Officers were out and about from 9pm until 3am in a bid to meet as many people as possible who could have been in the town centre two weeks ago and could have seen Mr Griffiths.''

He added: "The response we have had has been very useful and will be followed up."
