The Queen was warmly applauded today as she officially opened the new Bradford South Police Headquarters.

Her Majesty unveiled a plaque in the building to mark the official start of operations at Trafalgar House.

Accompanied by the Duke of Edinburg she then signed a special scroll at the end of her 45-minute visit to the headquarters.

The Queen was greeted by a crowd of around 100 onlookers, some waving flags and holding flowers, as she arrived at the modern new building in Nelson Street.

In the foyer she was introduced, by West Yorkshire Police Authority chairman Councillor Mark Burns-Williamson to senior police officers and civic dignitaries, including the divisional commander, Chief Superintendent Sarah Brown and the Bishop of Bradford, the Right Reverend David James.

She was then led on a tour of the headquarters by Chief Superintendent Brown before going outside to witness a dramatic demonstration by police dog Symba and his handler PC Ian Worrall.

The six-year-old police dog demonstrated how to arrest a suspect in a five-minute demonstration which had the Queen smiling and asking questions of handler PC Worrall.

During her tour the Queen had a private meeting with the widow of former Chief Constable Colin Cramphorn in which she presented her with his posthumous CBE.

Lynn Cramphorn, who met Her Majesty with her two teenage sons, said it had been a proud day for her. Mr Cramphorn, who was given the honour in recognition of his services to policing, died from prostate cancer last November at the age of 50 soon after stepping down from his post.
