An obsessed stalker who bombarded journalist and millionaire’s daughter Jemima Goldsmith with tweets and sent a mini-cab to her door for an imagined date has been sentenced.

Conor Donal O’Mahony, 60, of Pittock House, Freemens Way, Deal, had pleaded guilty at Hammersmith Magistrates Court.

He admitted one count of harassing Miss Goldsmith - identified in the charge as Mrs Khan - on September 27, last year and has now been banned from contacting her and going within 200m of her Chelsea home or visiting her Marylebone office.

When sentencing O’Mahony to probation, Deputy District Judge Adrian Turner told him: "That taxi arrived with the intention of taking her to a restaurant and must have made Mrs Khan extremely concerned about you, someone who keeps persistently tweeting her, and wondering what would come next.

“That’s the harm this offence causes. She had no way of knowing about your problems that lay behind the behaviour.

“The tweeting has stopped, you are receiving treatment and I hope this has allayed her fears and concerns.”

“She was particularly concerned he ordered a taxi to her address because it showed he knew where she lives” - Deputy District Judge Adrian Turner

The court was told that O’Mahony had an adverse effect on the 42 year-old mother-of-two’s usual day-today activities by contacting her on social media and sending the Addison Lee taxi to her home address.

He sent the cab so she could meet him at a restaurant. He also sent and hand-delivered letters to her home and tried to talk to her over the intercom. In his sad campaign to contact her he bombarded her and her friends with Twitter and Instagram messages.

In 2015 he was cautioned by the police for tweeting her five times a day and approaching her outside a hotel and asking her out to dinner.

The court was told that he had been diagnosed as suffering from bipolar in 1999, and this was made worse by five years of skin cancer treatment and extensive dental surgery.

Prosecutor Miss Kerry McNulty told the court today: “Mr O’Mahony ordered an Addison Lee taxi to her home address, which was given instructions to drive her to a restaurant in central London.

“He sent her messages via twitter to meet him at this restaurant.

“She was particularly concerned he ordered a taxi to her address because it showed he knew where she lives.”

The probation order imposed on Monday includes a mental health treatment requirement and a 35 day activity requirement.

Jobless O’Mahony who lives on benefits must also pay £85 costs and an £85 victim surcharge.

And if he breaches the ban on contacting his victim he could face up to five years in prison.

Westminster-born Jemima was married to Pakistani cricket legend Imran Khan between 1995 and 2004 and is identified in the charge under her married name.

Her parents are millionaire financier Sir James Goldsmith and Lady Annabel Goldsmith.

Her brother, Conservative politician Zac Goldsmith, 42, recently lost his Richmond Park seat and failed in a bid to become Mayor of London.
