The warrants were executed on Thursday, 1 April by officers from the Specialist Crime Command which continues to investigate crimes being committed on encrypted mobile phones as part of Operation Eternal. Officers from the Territorial Support Group were also involved in the operation.
One man, aged 34, was arrested at address in Cranborne Close and a 54-year-old woman was arrested at West Way, Moggerhanger, both in Bedford.
They were both arrested for conspiracy to supply cocaine.
No one was arrested at the address on Milcote Street, Southwark. Officers found a quantity of pills at this address.
Those arrested were taken into custody suites in Bedford.
Detective Sergeant John Cowell, from the Specialist Crime Command, said: “The arrests made this morning will have a positive impact on dismantling this organised crime group (OCG) we are confident are involved in the supply of Class A drugs.
“The supply of Class A drugs is the fuel for violent crime that officers from the Met are committed to tackling. It remains our top priority.”
