POLICE are appealing for witnesses and information after an attempted burglary led to them discovering a four floor cannabis factory.

Officers with Suffolk Police were called to Sudbury at 3.05am on Thursday, January 7 after reports that a burglary was believed to be in progress at a property in North Street.

Upon arrival, the suspects are believed to have already left the scene in a van.

However, due to the circumstances, officers entered the building only to discover a fully equipped cannabis factory which stretched over four floors.

More than 200 cannabis plans were found in the building and removed by police.

Suffolk Police say further enquiries in the area are still being carried out as the investigation continues.

Now police are urging people with any information to come forward.

A Suffolk Police spokesman said: "Officers would urge local residents and businesses to be vigilant to suspicious activity and anyone with information about drug-related activity in their community should contact Suffolk police.

"The signs to spot include a strong or sickly sweet smell in the air; buildings with windows constantly blocked off; high levels of heat and condensation and the constant buzz of ventilation.

"Such operations would most likely have people coming and going from an address at unsociable hours too.

"Anyone with information or who may have witnessed a van in the area in the early hours of today, Thursday 7 January, should contact Suffolk police, quoting crime number: 37/1004/21

"Members of the public who have concerns or information regarding the production or sale of illegal drugs in their community, should contact their local policing team.
