Zoltan Lakatos, 38, was caught by police in Leicester who found he had a staggering 10 people in his Audi A4, including the four youngsters shut in the boot.
The car had three adults and two other children on the back seat, and an adult passenger in the front.
Lakatos was convicted at Leicester Magistrates' Court of using a motor vehicle to carry passengers in such a way as to create a danger of injury to them and of driving without insurance.
Shocking! Who would EVER shut anyone - let alone four children - in the boot of a car!
