This is the moment police swooped on a gang of samurai sword-wielding teenagers suspected of carrying out dozens of robberies on the London Underground and trains.
Detectives believed the six - all under 18 - are linked to 51 offences where mobile phones and luxury watches were snatched in just two months across east London.
The Standard had been invited to join scores of officers - many in riot gear - as the family home of a 15-year-old boy was raided in Newham just before 3am.
As a force drone hovered in the skies, 200ft below they stormed through the front door ordering occupants to show their hands.
The youth is quickly located in his bedroom and shouts: “Relax, relax, relax.”
He calls out to his mother, who is screaming hysterically.
Once the teenager confirms his identity, officers yell “target secured” before he’s arrested and handcuffed.
British Transport Police allege he terrorised nine passengers between West Ham station and Grays in Essex, trains passing through Bromley-by-Bow and on Docklands Light Railway services at Devons Road and Cyprus.
Two muggings happened on February 25 and five others on March 13 alone.
The suspect is forced to listen as an officer reels off a list of offences.
But as he becomes distracted and fidgets, a police colleague interupts: “It’s probably best to listen to it.”
Asked if he understands the allegations, he replies “Nah” before being reminded not to stress out his mother further.
Body-worn footage shows police finding a samurai sword in a wardrobe in his brother’s bedroom.
As part of a separate Metropolitan Police investigation, the boy appeared at Stratford Magistrates’ Court last month in relation to 10 robberies - some at knifepoint - on buses in West Ham and Prince Regent, and breaching bail conditions by not attending school.
Later, officers smashed down the door of a townhouse where a 16-year-old boy lives with mother and sister in Dagenham shouting: “Police, stay where you are.”
Neighbours, awoken by commotion at 4am, later thank police for their transparency when asked about reasons for the raid. He is led away in handcuffs and a grey tracksuit.
At a third address, police video shows a second sword being seized at the home of an aspiring footballer aged 17.
His parents have to be held back as they challenge officers. The boy claims: “I haven’t been out in months. I have an ACL (anterior cruciate ligament) injury.”
The mother repeats his false story. She tells him to go with officers but warns her son as he continues to speak: “Shut your mouth”.
Thirteen arrests were made during Opertion Flycatcher, a week-long blitz last month. The six arrested on July 16 have been bailed until October.
Chief Inspector Nicholas Brandon said the crackdown was launched after figures revealed under-18s made up 72 per cent of 675 known robbery suspects in London and the South East. They include 11 and 12-year-olds.
Of that large cohort, 101 juveniles are linked to multiple robberies and one of them to 19 offences.
A 10-year-old is their youngest victim and the oldest 86, according to BTP.
Robbery is down 17 per cent in London but the capital still accounts for nine out of 10 of such crimes UK-wide.
Ch Insp Brandon said: “We are extremely conscious that robbery is a high harm offence. It causes an awful lot of fear and distress to the travelling public.
“The purpose of operations like this is to demonstrate that if individuals do come on to the network to commit such offences, we will track you down and execute warrants at your address with the aim of putting you before the courts.
“We’re talking about mid-teenagers and two swords that they’ve had in their bedrooms. It’s quite worrying they are carrying these weapons around.”
:: Anyone who is a victim or witnesses a robbery on the railway network is asked to contact BTP by texting 61016 or calling 0800 40 50 40.
In an emergency, always dial 999.
The force advises commuters to be mindful and aware of what’s going on around them. You are less likely to be targeted if you look confident and move with purpose. Keep mobile phones and valuables out of sight.
Switch on or install a tracker application on your smartphone, which could help trace the device if it’s stolen.
