'Operation Crackdown' In Bournemouth
Police in Boscombe have targeted suspected drug dealers and associated criminality in an operation in the town; with 11 warrants executed in the last two weeks and 18 people arrested.
Operation Crackdown, part of the Dorset Police's county wide Operation Dismantle, has now been running for one year; with officers utilising community intelligence to target suspected individuals.
In the last two weeks officers executing warrants as part of Operation Crackdown have seized a large amount of substances believed to be heroin and crack cocaine, and have closed down an address found to be cultivating cannabis plants.
Property believed to be stolen from a recent burglary has also been recovered as well as a large amount of money which is believed to be from money laundering operations.
Some of the 18 people arrested have been charged and others have been released on police bail, pending further enquires.
The charges cover a range of alleged offences including possession with intent to supply drugs, possession of drugs, production of cannabis, money laundering, burglary and handling stolen goods.
Chief Inspector Chris Weeks said: "I want to send out a clear message to those who sell and use Class A drugs in Boscombe that Dorset Police will not tolerate drug activity and every opportunity will be taken to seek out those involved in it.
"In the year since the commencement of Operation Crackdown, 71 Misuse of Drugs warrants have been executed; resulting in 81 arrests and 11 alleged offenders charged.
"The community has formed an integral part of the success of this operation providing a steady flow of information to the police.
"I would like to thank all those members of the public that have helped us, their community spirit has been commendable.
"I would encourage anyone who has information or concerns about alleged drug offences to contact the police in confidence.
"Together we will continue to tackle this problem and reduce crime."
Witnesses and anyone with information should call Dorset Police in confidence on 101. Alternatively, call the free and anonymous Crimestoppers line on 0800 555 111 where mobile phone tariffs may apply.
Violent crime was up 37% in the last year. Police say it's mainly due to a change in how offences are recorded.
