Daniel Rotariu, 31, and Katie Leong (pictured) were in a relationship at the time of the attack

A woman who attempted to kill her partner by pouring sulphuric acid on him as he slept has been jailed for life.

Daniel Rotariu lost his sight and was badly burned and disfigured when he was attacked by 52-year-old Katie Leong in July last year at the house they shared in Turner Road, Leicester.

Mr Rotariu, 31, and Leong were in a relationship at the time of the attack, when she poured acid at 96% concentration onto the victim for six seconds.

Leong and her former boyfriend, Mark Cummings, were both accused of attempted murder with Mr Cummings cleared by the jury at Leicester Crown Court on Tuesday.

The court heard Mr Cummings, 46, had ordered the acid online - but that the attack was 'driven and orchestrated' by Leong who was found guilty of attempted murder and will serve at least 17 years.

Angela Clark, from the Crown Prosecution Service, said: 'The evidence revealed a picture of her fascination with attacking someone using acid, including her possession of a book written by an acid attack survivor.

'We had scientific evidence that she was present when the acid was used, including traces of the acid on her clothing.

'The evidence of forensic medical experts confirmed that the acid was poured for about six seconds, and that a smaller dose of acid could have been fatal.

'All this evidence clearly showed that she had planned and implemented the attack fully intending to kill, so she was prosecuted for attempted murder.'

Ms Clark added the attack had a 'devastating effect on the victim', who is still undergoing treatment for his injuries.

She said: 'In order to avoid being blamed for the attack, Leong attempted to incriminate Mark Cummings, who wanted more than anything to resume their relationship.

'However, our case was that she was the driving force behind the attack and the jury decided that Mark Cummings was acting under her controlling influence, so was not guilty of attempted murder.'
