CTV footage shows a group of concerned women taking action when they suspected a man was trying to drive a vehicle when it appeared he was “unfit” to do so.
The worried passers-by are shown struggling with the man to grab the car keys off him, after he parked on double yellow lines outside a convenience store.
The incident happened around the time the nearby Havelock Academy in Cleethorpes, North East Lincs., was closing for the day.
Humberside Police officers, who hailed the actions of the group, responded to the incident and seized the car which was taken to a compound.
A nearby shopkeeper, who also helped stopped the man from driving off, said: “If he had driven off and hit a child, bearing in mind it was near school closing time - how could you live with your conscience?
“If it had not been for the other mums we would not have stopped him - all I could think of was what could happen if he drove off.”
