Police attend the scene at the Kings Road lorry park in Immingham, where a man's body was found yesterday morning.
Detectives are trying to piece together how the man, who has not been identified, suffered fatal injuries – but say not much is known at this stage.
As reported on www.thisis grimsby.co.uk, the man's body was discovered at the lorry park in Kings Road at about 6.10am yesterday.
Lorry drivers who had stayed at the park were forced to remain there as police carried out their investigations into the afternoon, forcing many to miss ferries.
Officers had to call in translators to speak to the drivers at the park, many of whom were Eastern European.
Forensic teams were at the scene, with a white tarpaulin erected where the body was found.
It is thought one of the lines of enquiry officers are pursuing is the man was hit by a lorry in the park and that the driver was unaware of what happened.
Detective Chief Inspector Bob Clark said: "We are currently trying to piece together the events that led to this man suffering fatal injuries in the truck park in Kings Road, Immingham.
"This is a busy part of Immingham that sees a lot of freight being transported to and from the docks by drivers from a number of different countries, many of whom may have stopped overnight in the lorry park.
"It is possible the death of this man was a tragic accident. However, not enough is known at this time to determine how the incident happened.
"It is vital any drivers in the area at the time who may have witnessed the incident or anyone with information contact us right away.
"Any information, no matter how small it may seem, could be vital to our investigation at this stage."
Anyone with information should call Humberside Police on 0845 6060222, quoting log 255 of June 28.
