Call to weed out drug factories

More than 120 cannabis factories have been found in one London borough since April, police say.
Officers in Newham want the public to alert them to anything suspicious because their resources are stretched after the terror attacks.

Each factory houses high-grade plants, known as skunk, capable of producing about £500,000 of the drug every year.

They are often run by criminal gangs and police think the area has been targeted due to cheap property prices.

The gangs usually tap into power supplies for other properties to run the special lights needed for the plants to grow.
