The five-strong gang that boarded up a commuter rail station in a burglary attempt were dressed in rail workers' orange suits.
British Transport Police have released CCTV images of the men who tried to break into a cash machine at Enfield Chase station in north London yesterday morning.
The station was closed during the morning rush hour after the men boarded up the entrance.
But they could not break into the cash machine and left empty handed having caused thousands of pounds worth of damage.
The still images show a number of men, their faces deliberately obscured by dust masks, dressed in orange high-visibility railway workers' clothing, who officers want to trace.
We now believe a group of five men, dressed as railway workers, gained entry to Enfield Chase station via the railway line in the early hours of Monday morning. They obscured several CCTV cameras and boarded up the station entrance to avoid being disturbed while they set about attempting to break into the cash machine with power tools. Despite a determined effort, they were unsuccessful and left empty handed.
