County lines drugs trade
Police say they are still tackling county lines drugs gangs amid the coronavirus pandemic.
Officers from the West Mercia force said offenders were continuing to exploit young or vulnerable people, using sophisticated grooming techniques to coerce them into selling drugs.
Ch Supt Tom Harding said: "I want to send a clear message to county lines drug gangs exploiting young and vulnerable people in our communities that despite the country being in lockdown we are continuing to focus our efforts to target them."
The force added that the past few weeks had been "very difficult" for young people and that some may have noticed individuals "still going out and meeting up with older people", or starting to "talk about expensive gifts they have been given".
