Two knives and a haul of class A drugs were also recovered and a total of eight people arrested as part of the operation, police revealed yesterday (March 13).
Officers from the County Lines Taskforce were waiting at stations when they spotted a teenager acting suspiciously as he approached the station.
After a chase he was detained and a search revealed a quantity of cannabis and cash.
But it was during a search of his bedroom that officers found a gun hidden inside a pizza box as well as cocaine.
He was charged with possession of a firearm, being concerned in the supply of cocaine and being concerned in the supply of cannabis.
Three others were later charged:
-
Edward Kpakra, 24, of Lower Road, Belvedere and Matthew Simon, 28, of Knights Manor Way, Dartford were both charged with possession of a bladed article.
-
Kelly Aghedo, aged 18, of Latham Road, Bexleyheath was charged with being concerned in the supply of Class A drugs.
The operation was joint effort by the British Transport Police and Kent Police.
British Transport Police Detective Inspector Ian Henderson, who led the operation, said: “This was yet another success story for the public who use the railway and the communities they live in with dangerous weapons taken off the streets as well as a substantial haul of drugs.
“The expertise of our County Lines Taskforce working in partnership with local police forces ensures that our resources are targeted to areas where individuals peddle drugs and weapons on the rail network.
“This was a high visibility deployment to deter and disrupt criminality on the railway but we work around the clock, day in, day out across the country.
“You don’t have to see us to know that we’re there.”
