Police officers and Dogs Against Drugs have seized heroin, cannabis and ecstasy during a number searches over the weekend.
On Friday a house in the Lerwick area was searched and a cannabis seized. A 29-year-old man was arrested and charged with concern in the supply of drugs. A report will be sent to the procurator fiscal.
On Sunday morning a 38-year-old man was stopped and searched as he disembarked the ferry from Aberdeen. Heroin with an approximate street value of £16,000 was seized. The man remains in custody and a report has been sent to the fiscal.
Chief inspector Lindsay Tulloch said: “In total, three houses have been searched, two people have been arrested and charged with being concerned in supply controlled drugs and four people have been charged with possession of drugs.
“This reinforces our commitment and ability to act on information provided by the community. If the public continue to phone in and support us with information we can deter people from carrying drugs to Shetland and reduce the availability of drugs in the community.
“Being found in possession of drugs or any other involvement in the supply of drugs can lead to a significant jail sentence, I would urge anyone to think twice before they get involve in drugs.”
