New video has been released showing a Spanish lorry driver apparently helping migrants or refugees from the back of his truck at the Dartford Crossing in Kent. It was taken by another driver travelling on the M25 who was stunned by what he saw. He called the police but by the time they got there there was no trace of the driver or his human cargo. The trucker's employers have since told us he was unaware anyone was in the back of the lorry until he heard noises. Nashreen Issa reports.
