The five-strong gang that boarded up a commuter rail station in a burglary attempt were dressed in rail workers' orange suits, police believe.

British Transport Police (BTP) has 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, causing considerable travel difficulties, 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.

Officers continue to appeal for witnesses to come forward and are keen to hear from local residents who saw workmen on or around the station last weekend.

BTP Detective Sergeant Alan Bardsley said: "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."

Mr Bardsley added: "We are confident someone out there knows who this group is. Their act of boarding up of the station entrance caused considerable disruption to morning commuters trying to use the station. Those responsible are determined criminals and we are doing all we can to catch them before they strike again."

Anyone with information is asked to contact British Transport Police on 0800 40 50 40, or text 61016, quoting E/B5 of 15/06/2015. Information can also be passed anonymously to independent charity Crimestoppers on 0800 555 111.

Roger Perkins, from the Great Northern train company, said: "Passengers suffered a frustrating start to the week following the break-in at Enfield Chase, a station used by 1.3 million people a year.

"None of our trains were able to stop there until 8am but our staff worked hard to reopen the station as quickly as possible."
