A distressed mother has accused police of 'pure abuse of power' after they arrested and handcuffed her son and another youngster right in front of her.

The boys, both understood to be 10 years old, were approached by Cumbria Police officers in Kirkby Lonsdale yesterday morning after reports that a member of the public had been threatened with a penknife.

However, following an extensive search no knife or other weapon was found and the boys were released.

Cumbria Police later said in a statement they had been handcuffed 'for their and officers safety while the searches were completed.'

But footage of the incident shows one of the boys clearly becoming agitated after being handcuffed - with his mother also becoming tearful at the sight of her detained son.
