This was the chilling 999 call made to emergency services, from a desperate group who were allegedly trapped in a refrigerated vehicle.

In audio released by Cambridgeshire Police, a man could be heard telling the call handler "we are dying, can you help us please?".

When asked what the issue was he responded: "The lorry is cold. We are dying by cold. We don't know where we are."

He added: "We have two underage, like 16 or 17, they are dying. Please. We have woman. Pregnant. She's dying. With the cold, she's dying."

He revealed the group had been stuck inside the lorry since midnight the day before and had been banging on the side of the lorry for three hours.

The driver was initially arrested on suspicion of human trafficking but later released with no further action.
