Cafe bosses are asking rail chiefs to step up security at a busy railway station after suffering their second burglary in two months.

Stephen Greener, who runs Ruth's Whistle Stop at Shipley Station with his wife Ruth, says he fears they may eventually be forced out of business unless the break-ins are stopped.

In the latest incident thieves hurled part of a paving slab through a window of the cafe before grabbing stock worth hundreds of pounds. A CD player was also stolen.

Mr Greener, who took over the business last September, said: "We didn't open on Tuesday because of it and so lost a day's trade.

"We're not giving up - but you can't keep losing stock like this when you're in business and if it carried on happening we wouldn't be able to continue sustaining losses of this kind.

"I'll be getting in touch with Arriva Trains Northern to request a meeting so we can talk about what joint security measures we can take to stop this happening again and how to improve security throughout the station.

Among the ideas Mr Greener plans to put to Arriva are a new CCTV system and security staff to patrol through the station at nights.

Rowland Dale, of the Aire Valley Rail Users' Group, said: "We pressed very hard to get a cafe at the station because it was a facility that was badly needed.

"They are an excellent couple who provide a wonderful service but we risk losing it altogether if we can't stop this sort of thing happening.''

A spokesman for British Transport Police said the break-in at the cafe was being investigated.

Peter Cushing, regional director for Arriva Trains Northern, said the company was committed to helping tenants to improve security.

He added: "The lease clearly states that the overall responsibility for security within the premises lies with the tenant.

"However we do have a small budget available to help with security measures.

"We have spoken to the tenant previously and made recommendations and it was suggested that we could help with the installation of an alarm to the premises concerned, and we are waiting for the tenant to contact us."
