Superintendent Tracy Bradley of Humberside Police has told the Grimsby Telegraph:
What we know so far is that a collision has occurred between a Nissan Primera and a light goods vehicle. There were five occupants in the Nissan Primera, and two of the occupants were taken to the Diana, Princess of Wales Hospital where they were declared deceased.
There were three other occupants of the vehicle who were certified deceased at the scene.
At this moment in time we are conducting an investigation to try to find out what the cause of the incident was, and we have family liaison officers that are working with family and relatives of the deceased.
We would like to appeal to any witnesses that either saw any of the vehicles prior to the collision or saw the incident occurring.
