A young boy is locked in a Subway store by a worker in this shocking footage after a row broke out over an alleged stolen packet of crisps.
The boy, believed to be aged 10, gets more and more upset throughout the footage and tries to get out of the locked restaurant in Wembley.
In the clip another youth dressed in a grey tracksuit with his hood up repeatedly kicks at the door, before picking up a heavy advertising hoarding and throwing it at the glass.
As the trapped boy is picked up by a male member of staff his friends rush even more frantically to smash through the door.
But after it does not budge the struggle continues inside the branch as the trapped youngster comes back into shot but is dragged across the floor by the worker.
The footage was uploaded to Facebook on Sunday and had received around 7,000 views.
One Facebook user wrote: "Old fashioned way is to beat the kid yes, but it's 2015 and you can't man handle a little boy like that, the worker made a wrong decision on this one."
A Subway spokesman said the incident is currently being investigated.
A Met Police spokesman said: Police were called to an allegation of shoplifting and criminal damage at 1.09pm on Sunday, November 22 to a commercial premises on Bridge Road, Wembley.
"Damage was caused to the door of the premises, no arrests have been made at this stage however enquiries continue."
