Criminals exploit children as young as nine to courier crack, cocaine, heroin and cannabis via Stratford’s transport hub to smaller UK towns and cities.
Detective Superintendent Craig Payne, who leads British Transport Police’s specialist Taskforce, said the two-day “zero tolerance” blitz sought to identify individuals concealing illegal blades and substances.
On Tuesday, 30 people were searched after a positive reaction from dogs or refusing to walk through a metal detector, and 15 vulnerable young people safeguarded.
One person was arrested for supplying Class A drugs, another for travel fraud and a third detained under the Mental Health Act.
The following day, four males were held for offences including suspected Class A supply, breaching a criminal behaviour order, illegal entry into the UK and assault of staff at Stratford. Around £2,000 in cash was seized.

Speaking at the station close to Westfield Stratford City shopping centre, Det Supt Payne told the Standard: “Operations like this are conducted every day.
“If you chose to use children to conduct your criminal enterprises then we will find you and pursue you through the courts.”
Amanda Radley, BTP’s child safeguarding lead, added: “We have seen nine-year-olds being exploited through county lines. It just goes to show how children are vulnerable by virtue of their age.
“They don’t understand what they are involved in or maybe the threats being made against them are so strong.”
Ms Radley urged those in debt to gangs to seek help from independent partner agencies such as Catch 22 or St Giles Trust who offer one-to-one support for anyone thinking of exiting a gang.

She added: “You may have been told you won’t get help or had threats made against you or your family, but there are services out there. Speak to a trusted adult.
“We will be keen to seek those perpetrators abusing you. This is child abuse and we should have zero tolerance towards that.”

Illsley was identified through phone messages and arrested at his girlfriend’s address, Stafford Crown Court heard.
Det Supt Craig Payne said: “Illsley is a nasty individual, who, despite being a father himself, coerced and exploited children into travelling miles from home to sell drugs.”
Dealers like Illsley are often shocked that a conviction for modern day slavery can result in them serving prison sentences on a sex offender wing.
