In an unnoticed moment, a four-year-old child climbed behind the wheel of a parked car in Monaco and seriously injured a passerby on a short drive.

As the French broadcaster France Info reported with reference to the police, the man was operated on Saturday night.

He was therefore under the wheels of the car.

According to the report, the child had initially sat in the back seat.

When the driver of the car was about to hand over the keys to the driver of his hotel, the child sat behind the wheel and accelerated.

The vehicle then made a leap forward, hit the passer-by coming out of the hotel and finally hit the curb.

The police are now investigating how the car could accelerate without a key.
