A Wembley man and his brother who violently robbed a number of victims have been jailed after the heroic actions of a 10-year-old boy.
Brothers Devlin Williams, 33, of Hirst Crescent, Wembley, and Eugene Williams, 36, of Station Road, east London, were imprisoned for a spate of robberies across the capital.
One crime saw the pair rob Tania Levenfiche, 48, at her home in Wildwood Road, NW11, after arriving home on June 13 last year with 10-year-old son, Didier Levenfiche.
Footage shows the brothers grab the woman around the neck, placing her in a headlock and pulling violently at her ears, before snatching her jewellery.
Didier witnessed the entire incident, which also saw the brothers kick the family dog, and memorised their faces and activated the house alarm.
Met Police said his actions led to police identifying the brothers, prompting officers to name Didier Westminster Police's hero of 2016.
Devlin Williams pleaded guilty to one count of robbery on June 13 last year, and two separate offences of robbery on August 4 and 7 later that year.
He was jailed for six years and eight months, with his licence extended for three years.
Eugene Williams pleaded guilty on December 8 last year to robbing four women between November 19, 2015, and June 13, 2016, as well as possession of criminal property.
He was jailed for eight years, with his licence extended to three years.
Another man, Hatim Nahal, 31, of Kingshill Drive in Harrow, a Devlin Williams accomplice in the robbery on August 7, pleaded guilty to that offence on March 27 this year.
He is due for sentencing on Wednesday (May 3).
Detective constable Martin Thomas, the investigating officer from Westminster's crime squad, said: "Eugene and Devlin Williams are dangerous criminals who targeted innocent people across London.
"Thanks to Didier's attention to detail, both men were arrested in August 2016 and successfully picked out at an ID parade.
"Didier's brave actions directly led to them being brought to justice and we are very proud to have named him as our hero of the year."
Didier's mother added: "My son did not know what to do as he stood helpless but thank goodness had the sense of mind to push the panic button.
"As he said to me after the attack 'Mummy I felt so bad I couldn't save you'.
"He has since had continuous nightmares about the attack and is so scared to get in and out of the car in our driveway at any time of the day or night.
"He has not slept a whole night since the incident and also is very disturbed by the fact that the attackers kicked our dog over and over as she tried to jump up at them to help me.
"Please remember that he watched this whole incident and the face of the attacker staring at him."
She continued: "The Westminster Crime Squad and in particular Detective Martin Thomas have done an amazing job in piecing together this jigsaw.
"Martin and his team have spent countless hours which have turned into days and then months putting together clues that could have been insignificant to anyone else but which through their determination and hard work have created the result that we all wanted."
