The prostitute daughter of a 62-year-old woman stabbed to death in a street brawl at the weekend was murdered almost 12 years ago, the Telegraph & Argus can reveal.

Police were called to the home of grandmother Monica Flaherty, in Priestman Street, Manningham, at 3.25am on Saturday. She had been stabbed in the street, but managed to get back to her home where she died from her injuries.

Police continued to guard the modern terrace house yesterday and a post-mortem examination has revealed the pensioner died from a single stab wound to the chest.

On August 23, 1990, Mrs Flaherty found her daughter - mother-of-two Sharon Flaherty - stabbed to death in a flat in Westcott House, Green Lane, Manningham. The vice girl had been stabbed 14 times in a frenzied attack.

The 31-year-old single mother, who lived in nearby Montgomery House, left two children - an 11-year-old and a 13-year-old who, following their mother's death, were cared for by their grandmother.

It has also emerged that Monica Flaherty was given a 12-month conditional discharge in August 1991 for loitering for prostitution.

She was also jailed for a month in January 1998 at Hull Crown Court after she admitted supplying cannabis resin to Joseph Cawley, 37, when she visited him at Full Sutton Prison, near York, where he was serving a life sentence for murdering her daughter in a drunken rage.

The court was told she had a long list of previous convictions for offences including assault, handling and criminal damage.

During Cawley's trial at Leeds Crown Court in September 1991, Mrs Flaherty told the court she had been having a sexual relationship with him. It was revealed that both Cawley and Sharon Flaherty had drink problems.

Neighbours of Monica Flaherty described her as friendly but quiet.

One woman, who would not be named, said she had heard a commotion early on Saturday and had heard Mrs Flaherty's grandson shouting to someone to "get an ambulance - my nan is not breathing".

The woman said: "She lived there with her two grandchildren and was the first to move on to this street when it was built. She could be quite friendly if she wanted to and would shout 'Hello' if she was in the mood - if she wasn't, she wouldn't talk to you."

Another neighbour, who also would not be named, said: "I only knew her to look at, but it is a real shock."

Howard Brown, 35, of Bradford, was due to appear before Bradford magistrates today, charged with Mrs Flaherty's murder. Four men and a woman who were also being questioned in connection with her death have been released on police bail pending further inquiries.
