Four men from Ealing have been jailed for their part in a violent burglary where a victim was bound up and stabbed twice.
The Metropolitan Police said the gang used "extreme violence" and that the victims of the crimes "awoke to a nightmare scenario of intruders inside their home".
Police officers came across a "horrific scene" after being called by one of the victims, who were tied up by the armed defendants.
The four Ealing men had pleaded guilty to aggravated burglary, grievous bodily harm, possession of a firearm with intent and two counts of false imprisonment in relation to the burglary in Walthamstow in December 2016.
Snaresbrook Crown Court sentenced Mohammed Ramjhun, 32, of Seaford Road to eight years in prison, while 29-year-old Usman Deen of Seacole Close was given eight years.
Hoopang Wong, 30, of Byron Way was jailed for 12 years and 33-year-old Andy Chu of Southdown Avenue was jailed for eight years on Monday (September 11).
A fifth man, 36-year-old Kazm Kareem, of no fixed abode, was tried at the court and given 12 years in prison on the same charges, while the ringleader, 32-year-old Aso Mohammed Ghadr was given a 15 year prison sentence for conspiracy to commit aggravated burglary.
It is believed Ghadr, of Kedleston Walk, Bethnal Green, organised the violent robbery after a previous dispute over money with one of the victims, the police said.
Phone records showed communication between Ghadr and the other men, suggesting some degree of pre-planning.
Police said a number of men broke into a house in Warner Road in Walthamstow at around 4.55am on December 29, 2016 where they tied up two of three victims, stabbing one of them twice.
One victim managed to call police and alert them to a burglary on the road but did not give a door number.
Police came across the house with an open door and spoke with an unidentified man who was leaving the house.
They found one victim lying on his stomach with his arms and legs bound, who said that one of the the suspects was armed with a gun.
A police officer spotted three of the burglars as well as a second victim, who had blood on him.
He drew his taser and ordered the men on the ground, with Wong, Ramjhun and Deen complying.
Chu and Kareem attempted to run but a second officer stood in the doorway with his taser drawn, and detained the men.
The suspect's gun was later found to be an imitation and a number of knives were also recovered from the burglars.
The victim, who had been stabbed, was taken to an east London hospital suffering wounds to his back, neck and right arm and continues to have restricted movement of his right hand.
The initial five suspects were arrested on December 30 on suspicion of aggravated burglary, grievous bodily harm, possession of a firearm with intent and two counts of false imprisonment, while Ghadr was arrested three months later and charged on April 12.
Detective Constable Lee Warrington of the Met's Flying Squad said: "This was a terrifying burglary in which these defendants used extreme violence.
"Their victims awoke to a nightmare scenario of intruders inside their home and they are still traumatised by the events of that night.
"The officers were at the scene very quickly and were faced with a horrific scene, but they acted extremely quickly and decisively to bring the situation under control and used proportionate force to detain the suspects, despite being heavily outnumbered.
"I would like to pay tribute to the victims for their bravery, courage and support throughout our investigation.
"These offenders have shown no remorse and I hope that the fact that they will collectively have 63 years to reflect on their actions brings a measure of comfort to their victims."
