British Transport Police (BTP) is appealing for anyone who recognises these trolleys.

It comes after an attempted theft of cable from the Channel Tunnel Rail Link tracks at Ebbsfleet.

The incident is believed to have taken place between 7.30pm on Monday, June 3, and 6pm the following day.

Around 180 metres of live cable was targeted, although nothing was taken.

Officers discovered two trolleys close to the tracks which they believe were going to be used to take away the cable.
