Officers Tweeted that they had discovered three separate factories in the town on the afternoon of Saturday, May 19.

They also Tweeted a picture from one of the cannabis factories.

The discovery forms one of a string of finds made recently by police of cannabis operations across the county.

Last week police seized more than 200 plants in Norwich and arrested two men during a drugs warrant.

A cannabis factory was also discovered in Great Yarmouth on Wednesday, May 9 after emergency services attended a property over concerns of a liquid in a property.

On Wednesday, May 2, police searched a home in Norwich and found rooms with rows of the plants growing beneath lighting rigs.

Last month, a dog walker lead police to one of the largest cannabis factories in the county in Felthorpe, in which police seized around 4,000 plants.

They were being grown in a number of old sheds and greenhouses - siphoning off electricity in the process.

This comes after news of more than 500 arrests being made under Operation Gravity, which launched in 2016 in response to an increase in serious violent crime linked to county line drug dealing in Norfolk.
