The husband of Savita Halappanavar has left his life in Ireland behind and relocated to the US.

Praveen Halappanavar endured the heartbreak of losing his wife and their unborn child 18 months ago at University Hospital Galway.

The engineer with medical devices manufacturer Boston Scientific recently finished up at the US firm’s Galway plant and is now based in Los Gatos, California.

The Irish Examiner reports Halappanavar had received hate mail, but stressed that Irish people had mostly been kind and supportive.

The “hurtful and abusive letters” had told him to “leave the country”, “mind his own business”, and to “clean the mess” in his native India, he told RTÉ Radio.

Mr. Halappanavar is suing the HSE and his wife’s consultant obstetrician, Katherine Astbury, arising from her death on October 28, 2012.

In papers lodged with the High Court in Ireland last September, the personal injury summons alleges that Ms. Halappanavar’s constitutional right to life was breached.

It outlines more than 30 issues of alleged negligence, which it is claimed led to her death.

Praveen Halappanavar came to Ireland in 2007 and a year later he married Savita, a 31-year-old dentist, also from India.

Savita became pregnant in 2012 and was admitted to Galway University Hospital on October 21.

She was found to be miscarrying but was not offered a termination. She died a week later, after miscarrying and contracting E.coli, leading to septic shock.
