Police in Walsall have arrested 24 people on suspicion of drug offences in the town as part of Operation Eliminate.
The arrests follow a series of raids across the borough carried out over the past week, in a crackdown on street level drug dealing.
So far, 20 people have been arrested on suspicion of conspiracy to supply controlled drugs, while 16 have been charged and remanded into custody.
Four people in custody were arrested on Tuesday morning on suspicion of conspiracy to supply controlled drugs. These include a 44-year-old woman arrested in Bentley, a 32-year-old man arrested in Palfrey and a 52-year-old woman and a 51-year-old man arrested in Walsall.
Officers have also discovered cannabis factories in Coalpool and Bentley.
Operation Eliminate is an ongoing operation in partnership with Walsall Council and other agencies, and was prompted by communities asking police to tackle street level dealing and anti-social behaviour.
CI Sally Holmes, who is leading the operation, said: "Our communities have asked us to tackle street level dealing – we have done that.
"Over the past week, we have seen a number of arrests, all for individuals who we believe are selling drugs on Walsall streets."
