Police have seized a haul of heroin worth £15,000 during an operation at a Shetland ferry terminal.

The drugs were recovered by officers at Lerwick Ferry Terminal on Tuesday.

A 33-year-old man has been arrested in connection and is expected to appear in court.

Police in Shetland are assisted by anti-drugs charity Dogs Against Drugs.

They regularly help officers carry out patrols at ferry terminals in the northern isles.
