Business pressures led to a devoted Bingley father stabbing himself through the heart, an inquest heard.

Andrew Wetherell was found on the floor at his Bingley home three months ago with a kitchen knife stuck in his chest.

Mr Wetherell, 41, and his wife Jennifer lived at the Moorfield Nursery School in Bramham Road, which they had bought two and a half years ago.

But pressures began to mount after they bought another nursery school in Baildon and Mr Wetherell was being treated for depression.

In a statement read to the Bradford hearing, Mrs Wetherell said her husband's mood had changed in the last three or four weeks as he felt he had let her down. The night before his death she took a sleeping tablet and was woken at 10am the next morning by their son.

She went into the lounge office and found her husband on the floor with a black, wooden-handled kitchen knife in his chest and blood on his wrist.

Mrs Wetherell's mother, Margaret Seaman, had travelled from Essex to spend some time with them.

In her statement, she said the night before he died Mr Wetherell looked "stressed" and "vacant".

She described him as a perfectionist and said the couple were devoted to their son.

Detective Inspector Gerry O'Shea, who investigated the incident, said he found no signs of a disturbance and nothing to indicate any suspicious circumstances.

A hand-written note was found nearby.

"I am totally satisfied that no other person was involved," he added.

Home Office pathologist Dr Kenneth Shorrock said the cause of death was a stab wound to the left side of the chest, which had passed between two ribs and pierced the left ventricle of the heart.

Although Mr Wetherell had been prescribed three types of drug, very low traces of only one of them were found.

Recording a suicide verdict, Bradford Coroner Roger Whittaker said the note that was found was indicative of Mr Wetherell's state of mind at the time.

The "anguish and depression that must have been in his mind" had caused him to take his own life.

It was sad that he had apparently not taken the medication he had been prescribed by the doctor, said Mr Whittaker.
