Police are trying to piece together the last known movements of a man whose body was discovered near a railway track in Flintshire.
Daniel Christopher Starr's body was found near the line between Neston, Cheshire, and Hawarden Bridge railway stations at about 08:43 BST on Monday.
The 20-year-old was last seen outside the Lady Hamilton pub in Neston on Sunday morning.
Police want to speak to friends who were out with him on Saturday night.
DCI Iain Miller, from British Transport Police, said: "I would like to emphasise that they are not in any trouble, but that we need to speak to them because they could assist our enquiries in piecing together Daniel's final movements."
Mr Starr was described as white, 5ft 3ins tall, of very slim build, with dark collar length hair. He was last seen wearing a green hooded top, a black Vans t-shirt, black jeans and 'Converse'-type footwear.
