Four people have been arrested following early morning raids.

Two men and two women have been arrested for drug offences after warrants were executed earlier this morning at three properties in Ramsbottom and Rochdale.

Part of 'Operation Foam' a man and a woman, both 31, were arrested in Ramsbottom and a man and a woman, both 28, were arrested in Rochdale.

All four were arrested on suspicion of conspiracy to supply controlled drugs and involvement in the activities of an organised crime group.

They all remain in custody for questioning.

Detective Inspector Karl Ward of GMP’s Operation Challenger Team: “The arrests today are the culmination of months of evidence gathering and dedicated investigative work and I extend my thanks to the Operation Challenger Team for the commitment they have put in to help disrupt this kind of activity.

“GMP is dedicated to disrupting and halting organised criminal activity, and we will continue to work to dismantle the networks involved in the distribution of drugs throughout our communities.”

A large quantity of money and 16 digital devices were recovered from the properties and will be examined.

The arrests form part of Operation Foam – which is the GMP strand of the NCA-led Operation Venetic – and has seen enforcement agencies across the country join together to target the use of a highly sophisticated encrypted global communication service being used by organised crime groups.
