Fracking protesters intercepted and climbed on top of a truck at motorway services last night, say police.
The truck was on its way to the Cuadrilla site on Preston New Road when its driver stopped at Forton Services near Lancaster on Sunday.
Police say they were contacted at around 10.30pm following reports of three protesters approaching the truck with one of them climbing on top of the wagon.
A spokesman for the police said: "We had some of the protesters from the fracking site climb onto a truck when the driver stopped.
"Three protesters are currently with the truck with one on top of it.
"Thankfully, there is no disruption to traffic.
"We will be monitoring the situation."
A spokesman for Frack Free Lancashire said: "The two protesters climbed on top of the truck when it was parked while the driver was in the services.
"They have done this to show that the protests against fracking are not going to go away and to slow down operations at the Preston New Road site."
