A CANNABIS factory was discovered yesterday after a passing police patrol smelt cannabis coming from a house in Blackburn.

PCSO Sarah Wilson was on foot patrol when she noticed a strong smell of cannabis coming from the property in Beardsworth Street, Little Harwood.

Officers raided the home and found 21 plants in an upstairs bedroom. The plants have now been seized along with cultivation equipment including lights and fans.

A man is now being interviewed in relation to the find.

PCSO Wilson said: “The smell was so strong I contacted the office and we were able to obtain a search warrant.

“It was a fairly sophisticated set up. The plants were fully matured and would have an estimated street value of £500 each. They had clearly been there for some time.

"Drugs cause misery to the lives of decent law-abiding residents as well as to those involved in the trade and we will continue to act on any information we receive, in confidence if people prefer, so we can take drugs and those suspected of peddling them off the streets.”
