A series of radio messages to organisers of Corby's Grow Festival forced them to cut short the final events of the successful event,
The festival - which has drawn crowds of thousands into the town - was due to finish with a Full Moon Party at the Corby Cube at 8pm last night (Saturday, February 8).
But that was cancelled, and the Museum of the Moon event forced to close ten minutes early when the threats were received.
A statement this afternoon from the organisers thanked the thousands of people who have supported the festival. It added: "On Saturday evening we took the decision to cut short the GROW festival after receiving a series of radio messages which required further investigation.
"After consultation with the police, the decision was taken to act in the interest of public safety and cancel the evening’s events.
"We now believe these calls to be malicious but not dangerous, however the safety of the public and event teams was our first priority. The adverse weather conditions had already affected some of the outdoor performances.
"We are thrilled at the fantastic support and turnout for the festival over the whole weekend and we are equally as disappointed as our tremendous audiences that the evening’s events were cut short.
"We are eternally grateful for the continued support of the people of Corby and all those who make the festival possible.
