Amir Mahmood, 25, jumped from the Leeds University Medical School building at Leeds General Infirmary a day after he was told he had failed his fifth year for the second time and was asked to leave.

When an inquest opened in June Mr Mahmood's father, Khalid Mahmood, said he believed his son had been harassed by a tutor at the university who had also been racist.

The medical school and the tutor, Richard Fuller, vigorously denied the allegations.

Yesterday, West Yorkshire Coroner David Hinchliff told the resumed hearing in Leeds, he could not find any evidence to support the family's claim.

After recording a verdict that Mr Mahmood took his own life, Mr Hinchliff said he also wanted to address the allegations, despite their not being a strict part of his inquiry.

He said: "I will place on record that I have heard no evidence to suggest that there is any credence in what has been said."

Mr Mahmood was told he would be expelled from the Leeds University course after failing his fifth year for the second time in June last year.

Mr Hinchliff accepted evidence that the student was not intellectually lacking, but had a long history of attendance problems which has never been explained.

The court was told he hoped to follow his GP father into the medical profession and wanted to be a doctor from the age of 11.

The inquest heard a series of allegations from his father, Dr Mahmood, of Rossendale, Lancashire, who said: "I think he was being harassed all the time through the year by Mr Fuller. There are some racist issues in this case as well."

In giving evidence Dr Fuller vigorously denied the allegations and the coroner heard that a university inquiry had completely exonerated him.

Dr Fuller said he had had a good relationship with Mr Mahmood and told the hearing: "I'm not a racist...some of my best friends are not white."

Yesterday, the coroner suggested Mr Mahmood "may have caused his family to believe he was the victim of bullying, harassment and racist remarks in some way to elicit their sympathy".

Det Sgt Paul Conroy of West Yorkshire Police, who led the investigation after Mr Mahmood's death, told the hearing that although the student had wiped his laptop's memory before his death, there was evidence still present that he had accessed suicide websites and chat rooms.

He said the death was not suspicious.

Mr Mahmood died after jumping from a window of the Worsley Building at Leeds General Infirmary, which houses Leeds University's Schools of Medicine and Dentistry.

Mr Hinchliff said it would have taken effort to get onto the window ledge and jump, and concluded the student had taken his own life.

Speaking outside court family friend Mohammed Malik read a statement on behalf of Mr Mahmood's devastated mother Nasiree.

He said Mr Mahmood should not have been allowed to receive information that he was being thrown off his course without a friend being there.

The statement added: "I go to his room every day and I cry. I can't believe my beloved son is gone.

"I won't see his face again. I won't be able to hold him again. What hurts more than anything is I think how lonely and desperate he must have been when he leapt to his death."
