Hunt for cannabis factory couple

Police found a cannabis factory at the four-bedroom house

Police in the Highlands are trying to track down a couple after they discovered a four-bedroom house which was being used as a cannabis factory.

The discovery was made at a house in a new development in Nairn.

The couple - a woman in her 30s and a man in his late 20s - have been described as being of south east Asian appearance.

She was said to be slim, with short, black hair and he was 5ft 5in, well-groomed and clean shaven.

The woman was last seen wearing leggings, ankle boots and a short jacket and the man was last seen wearing black trousers and a pink and white shirt.

Police said the the couple had answered a newspaper advert for the rented villa.

Officers warned landlords that other homes in the area could also be used to grow cannabis and have circulated a list of clues to recognising when a house is being used to grow the drug.

They urged the public to contact police if they see a house where windows are permanently covered from the inside, where there's a pungent smell and the sound of cooling fans, and where people who rent properties do not live there but only visit to maintain them.
