More details have been released after 13 people were arrested on suspicion of conspiracy to supply class A drugs in St Helens.
Officers carried out early-morning raids on properties across the town on Thursday November 10 as police tried to smash a huge drug-dealing operation.
Eight of the suspects are from St Helens, with a 35-year-old man, a 34-year-old woman, two 17-year-old males, a 42-year-old man, a 29-year-old man, a 47-year-old man and a 27-year-old man from the town all in custody.
Police also arrested two 25-year-old men from Thatto Heath, a 51-year-old male from Sutton, a 48-year-old man from West Park and a 25-year-old man from Clock Face.
A 25-year-old man and a 56-year-old woman were also taken into custody on unrelated drugs possession matters.
Police released video footage of the raids, which followed a six-month operation between the regional organised crime unit and St Helens CID.
Cash was recovered from two separate addresses, while a small quantity of class A drugs were found at two houses and class B drugs were recovered from another property.
Police also seized a motocross bike for forensic examination and also found a replica firearm at one address.
Merseyside Police said residents had become increasingly concerned about heroin and crack cocaine being sold and used in St Helens town centre and Thatto Heath.
