A mysterious humming sound has kept people in a Suffolk town awake for the last seven weeks

The hum, which has been heard in Sudbury overnight, has led to 50 people contacting Sudbury Town Council.

Lord Philips of Sudbury said: "If someone had said to me a spacecraft had landed on the meadows last night I would have said 'well I heard it'."

A council spokeswoman said Babergh District Council was attempting to identify the noise..

Sue Brotherwood, Sudbury town clerk, described the noise as a "high hum".

"The district council are doing their best to identify the source and have sent people out to try to hear the hum, she added.

Local community warden Bradley Smith was one of the first people to hear the sound.

He said: "Originally I thought I was hearing things.

"I was speaking to a dog walker who brought it to my attention and asked what it was.

"No-one knows what it is at present.

"We have all got theories behind it - some out of this world and some are logic, but no-one really knows what it is.

"It's a high pitched drone, continuous between about six at night and five in the morning and dependent on what age you are, determines what you interpret it as."
