This brazen - wearing a red polka dot onesie - is being sought by police.

The distinctive suspect was captured on CCTV on October 6 at Dewsbury Railway Station and is being linked to the theft of three monitors which are used to give rail updates to passengers.

Pc Marcus Robinson said, “We are releasing their images in that hope that, despite their faces being covered, someone may recognise their distinctive dress.

“One of the men is wearing a red polka dot onesie, the other appears to be wearing purple leggings and carrying a spade.”

“If you recognise them, have been offered one of the screens, or have any information that could help our investigation, please contact us.”

First TransPennine Express, who manage the station have now increased security measures on other screens at their stations to make them more difficult to steal.

Pc Robinson added: “The screens, which are expensive and will now have to be replaced, are used to provide up to date travel information to passengers at the station and usually only operate in a commercial environment. They cannot be used as televisions but they may be able to be hooked up to a computer or a gaming station which is one possible line of enquiry we are looking into.”

These images are the third linked offences which occurred on October 6 at 10.50pm.

Police believe further thefts occurred on October 3 and 5.

Anyone with information should contact British Transport Police on Freefone 0800 40 50 40 quoting B4 of 15/10/14. Alternatively call Crimestoppers on 0800 555 111.

The CCTV images show only part of the thief's face, but despite his onesie, he should be easy to identify.

However, not all photofits and e-fits are as helpful.
