Pictures of three boys building a barricade on a railway track where a passenger train was due in minutes have been released by police.

The children put a shopping trolley, tyres, tree trunks, traffic cones and concrete tiles on the line. Police, who dismantled the barricade, said it could have derailed the train. The boys, aged six, seven and nine, were filmed by a member of the public on the Liverpool to Manchester line.

Officers detained the boys but they are too young to be prosecuted.
