A GOOD Samaritan alerted police to an insecure front door – and helped uncover a cannabis factory in the process.

More than 100 plants were found at a terraced house on St Thomas’s Road when officers arrived to check out the wide-open property.

A kicked-in front door led police into the unoccupied house – between Folly Hall and Thornton Lodge – where they discovered two bedrooms and a cellar being used to grow the illegal substance.

The raid happened at around 8am yesterday morning near the landmark Huddersfield Christian Fellowship’s Cathedral House.

The value of the plants was still being investigated but is expected to run into tens of thousands of pounds.

No arrests have been made but police inquiries are ongoing.

Acting inspector Chris Sheard from Huddersfield South’s neighbourhood policing team said: “We received a telephone call from a member of the public about insecure premises on St Thomas’ Road.

“When our officers got there, they found the door already kicked in and discovered a cannabis factory.

“The house is unoccupied so there have not been any arrests but inquiries are ongoing.

“There were approximately 100 plants. We do not yet know how much they would yield.

“It depends on how many buds were on them and whether they were ready.

“We have taken samples of the plants from different stages of growth and they have been sent away and will come back with a value.”

He said the temperature inside the house was high. And he highlighted how criminals often tamper with electricity meters to conceal their extra usage.

He added: “That’s why these raids take time because we often have issues with the electricity supply.

“It wasn’t in this case, but because of the amount of extra electricity being used they do things to divert it so it isn’t obvious to the electricity company that someone is using an extra £3,000 a month.

“We often have to call someone out because properties are just not safe.”

He appealed for the public to be vigilant and to contact police with any concerns about premises.

The cannabis haul comes after several other raids have been made across Kirklees so far this year including Lockwood, Marsh Mills, Crosland Moor, Batley, Hipperholme, Dewsbury and Ravensthorpe.

Anyone with information about the factory or any other suspected drugs operation should contact police on 101 or call Crimestoppers anonymously on 0800 555 111.
