Firefighters were called out shortly after 2am this morning when traffic cones were set on fire in Knaresborough.

North Yorkshire Fire and Rescue Service believes the fire was caused deliberately.

Its incident log said the Knaresborough crew was summoned to King James Road at 2.13am, adding:

“Knaresborough crew have dealt with traffic cones on fire in the open.

“Crew used buckets of water and the cause is believed to be deliberate.”

No further details have been released.

Four weeks of roadworks began last weekend on King James Road and York Place in Knaresborough to enable Northern Powergrid to install electricity cables.

The junction of the two roads is due to reopen on Monday with four-way temporary lights in place until the expected completion date of Tuesday, June 20.

Quick-thinking traffic management staff averted a highly dangerous situation on a main road outside Harrogate’s Great Yorkshire Show this morning.

Staff at SEP Events, which is based in Boroughbridge, discovered 450 cones and 25 signs were missing when they arrived for work shortly before 6am this morning.

The items, worth thousands of pounds, are believed to have been stolen either by another firm or by thieves looking to sell them on. Several sources have confirmed the details to the Stray Ferret.

The cones and signs were taken at the Kestrel roundabout, which has been the busiest point for traffic during the show, and at the nearby junction of Wetherby Road and Rudding Lane.

The stretch of Wetherby Road between the two locations usually accommodates two-way traffic but a one-way system has been operating from 6am until 8pm each day of the show to improve traffic flow.

The cones and signs have played a key part in enforcing this.

But with the items missing, and 6.30am approaching, there could have been chaos with traffic heading towards the show from the Kestrel roundabout in both lanes meeting head-on vehicles travelling in the other direction that should have been diverted off Wetherby Road.

SEP employees had to stand in the road in high visibility jackets and use their vehicles to direct traffic while colleagues went back to Boroughbridge to get replacement cones and signs.

Shortly after 7am traffic measures were back in place and no accidents had occurred.

Traffic cones cost several pounds each and weigh about 6kg so whoever was responsible is believed to have had a trailer with a high load-bearing capacity.

North Yorkshire Police has issued an appeal for information. It said in a statement:

“The cones and signage were installed as part of traffic management for the Great Yorkshire Show and the theft led to significant disruption for motorists and showgoers.

“It is believed the items were taken between 9pm on Tuesday 12 July and 4am on Wednesday 13 July so police are appealing for anyone who might have seen anything which could help the investigation.”

The Stray Ferret has contacted SEP Events about the incident.
