A house building firm has come under fire after its failure to install street name signs on a new estate left an ambulance crew on an emergency call struggling to find an address.

Robert Turasz, of Osbourne Drive, Queensbury, dialled 999 after he and his partner, Catherine Walsh, found their 17-month-old son Callum feverish and barely breathing and feared the worst.

Mr Turasz, 23, an electrician, said he saw the ambulance crew arrive on the partially-built estate within minutes.

But when he looked out of the window he saw the vehicle driving up and down neighbouring streets, searching for the correct address.

As the couple prepared to go in search of the ambulance, a resident in a neighbouring street pointed crews in the right direction.

"You can't blame the ambulance crew - they were here within minutes, but without signs the streets are a maze," said Mr Turasz.

Callum was taken to Bradford Royal Infirmary and transferred to St Luke's Hospital, where he was kept in overnight for treatment. He has since made a full recovery.

Mr Turasz said: "The doctors say he had some kind of fit. His body seized up - for a moment we thought he was dead. It was a very scary experience. Fortunately, it turned out okay, but this should be a warning to the developers."

The family has been living on the Granby Fields estate for a year. Building work is continuing on three roads by Morris Homes, which has taken over from the original developer, Allen Homes.

The street names feature on new maps and well over half the properties are in use but Bradford Council said it is the developer's responsibility to put road signs up.

Today, a Morris Homes spokesman said the company regretted the incident and was working to put things right.

"Morris Homes' practice is to put up street signs once a road is completed. Many housebuilders do not put up signs until a road is adopted by the local council,'' he said.

"The local authority specified the roads would not be adopted until the widening of Granby Road was finished and this widening work will be undertaken once the development is complete."

An ambulance driver, who lives on the new estate but did not want to be named, said: "If you don't live here it's difficult to work out which streets are which."
