Armed Police at Lewes Bonfire Night
Sussex Police are deploying armed officers at the annual bonfire celebrations in Lewes.
The force say although there is no specific threat, because of the the national security threat they have decided to put extra security measures in place to keep people safe.
Chief Superintendent Neil Honnor said: "With our partners, we aim to ensure a safe environment so everyone can have an enjoyable evening.”
"Lewes Bonfire is a high-profile crowded event, and although there is no specific reason to believe it will be targeted we have to consider the potential security threat. There will be additional road closures and some armed officers at the event on the night. In the current climate it is not unusual for armed officers to be at an event of this size."
"Due to the national security threat assessment and the evolving nature of the threat we have reviewed our response, as other forces around the country are doing continually, and as a result, despite not having any specific intelligence, have put additional security measures in place."
In July, an ISIS terrorist drove his lorry into large crowds celebrating Bastille Day in Nice killing 84 people.
