Dawn raids see 8 arrested and discovery of crack cocaine, heroin and cannabis farm

Eight people were arrested in the dawn raids after warrants were executed in Bolton, Hyde, Ashton-under Lyne, Stalybridge, Openshaw and Rossendale.

Seven men – aged between 22 and 54 – and a 54-year-old woman were all taken to custody on suspicion of conspiracy to supply class A drugs before being questioned by detectives.

One of the men – aged 30 – is also being held on suspicion of the cultivation of cannabis.

As part of the warrants, officers seized a substantial amount of class A drugs – including crack cocaine and a quarter kilo of heroin – cash, and discovered a cannabis farm.

Further evidence was seized as part of detectives’ ongoing enquiries into the investigation – codenamed Headland, which began in March after reports of class A drug dealings in the district.

Detective Sergeant Ian Parker, from Greater Manchester Police's Operation Challenger which tackles serious and organised crime, described the importance of people contacting officers with information.

Det Sgt Parker said: "Today's action is the result of a thorough investigation into the supply of class A drugs – a crime which can ruin peoples' lives and blight communities.

"These investigations rely on intelligence from police, partners and members of the public.

"I would like to use this opportunity to thank those who have assisted us so far but also appeal to anyone else with information which may be of assistance to pass it on."

Anyone with information about the supply of drugs should contact police on 101.
