A statement from Thames Valley Police said: “Thames Valley Police was made aware of a third party report relating to a security concern at the Christmas Lights switch-on event in Market Square, Aylesbury.
“Officers informed the organisers of the event and they made a decision to close the event earlier than planned.
“Officers assessed the report, investigated the circumstances and have subsequently established there was no credible threat.
“An investigation in to origins of the report is ongoing.”
A statement from Aylesbury Vale District Council said: “Following police information, the decision was taken to finish Aylesbury’s light switch on activities slightly earlier than planned.
“The switch on itself was a fantastic event with thousands of people enjoying the start of the Christmas festivities.
“We understand that some people were disappointed that they couldn’t enjoy the post switch on entertainment but public safety must always be our priority.”
The decision left many parents disappointed with one mother telling us: “My kids were so disappointed that the rides and food stall finished earlier then expected.”
The event otherwise proved a great success with Aylesbury panto stars Su Pollard, Andy Collins and La Voix turning on the lights.
There was live music from acts including The Zefrones and Lucy Mair and a fireworks display to round off the evening.
