The aunt of tragic mum Teresa Innes today vowed to fight on in her niece's memory after police announced no hospital staff will be prosecuted.

Teresa, 38, pictured, died in 2001 after being given penicillin at Bradford Royal Infirmary even though she was acutely allergic to the drug.

Yesterday a statement from West Yorkshire Police who had been investigating stated no-one would be prosecuted in connection with her death.

Sheila Innes, Teresa's aunt, said today that, despite the lack of a prosecution, she wanted answers and hoped to get them now an inquest will be heard.

She said: "I am not very pleased. But the inquest will be next and I shall be there. I want to see the people who treated her face to face and get some answers.

"This leaves it all still unresolved and I have to carry on because Teresa would have wanted to get to the bottom of it.

"It seems basic checks were not carried out and if they had been Teresa would still be here today. They weren't and she isn't, and that is the tragedy."

Teresa, from Ternhill Grove, was admitted to hospital for treatment for an infected insect bite in September 2001.

A violent reaction to the drug caused her to suffer a massive heart attack which starved her brain of oxygen.

She fell into a coma and never regained consciousness. She died in August last year after the hospital was given permission to stop artificially feeding her by a High Court judge in London.

Mrs Innes, who lives in Bournemouth, said she accepted mistakes were made and did not want people to go to jail over it. But she said she wanted someone to have taken the blame.

She added: "Teresa's note said she was allergic to penicillin and she told them over and over again she was because she was so frightened about being in hospital. It defies belief it has happened. Now she is dead and gone."

She said she had had an apology from the BRI and urged them to make sure their checking procedures are tightened up.

"I find it very hard. I know mistakes happen and I can come to terms with that. But when three people are involved in her care and she slips through I can't comprehend that.

"I hope to come to Bradford for the inquest and ask some questions myself. Right now I feel no nearer closure on this. We shall wait and see what the coroner has to say. I hope to come face to face with them at last."

Teresa's death prompted a major police inquiry into how she came to be given the drug despite various measures being in place to prevent it happening.

It is understood there were warnings on her medical notes and she had been wearing an armband highlighting the danger.

As part of the police inquiry, four people, including doctors and nurses, were questioned by detectives under caution.

They could have faced charges of manslaughter and possibly jail sentences.

A West Yorkshire police spokesman said the file had now been passed back to the Coroner.

A force spokesman said: "The matter was referred to the police by Her Majesty's Coroner, and following advice from the Crown Prosecution Service a decision has been made that no persons will be prosecuted."

A spokesman for the Bradford Teaching Hospitals NHS Trust said: "We deeply regret the tragic events that happened in September 2001 and once again take this opportunity of expressing our sympathies to Teresa's family and friends.

"Since then, we have continued to work closely with the police as they have carried out their inquiries.

"We have been made aware of today's announcement and have informed staff about it.

"We will continue to co-operate fully with the coroner as he continues with his investigation.

"Until his inquiry is complete, and the forthcoming inquest into the circumstances of Teresa's tragic death is concluded, it would be inappropriate to make any further comment."
