The son of a woman found dead at her home in Kingston has been arrested in northern Spain.

Sean Heiss, 28, from Surbiton, was arrested by police in San Sebastian on a European warrant last Friday.

His mother, Margot Sheehy was found dead lying on her couch in her flat on Springfield Road in Kingston on June 12.

Detectives initially believed Ms Sheehy had died from head injuries but a postmortem examination later revealed the cause of death as asphyxiation.

A Metropolitan Police spokesman said: "On Friday 22 June a 28-year-old man was arrested on a European Arrest Warrant in San Sebastian, Spain, in connection with the murder of Margaret Sheehy in Kingston on 12 June.

"The extradition process will continue in due course with the man appearing in court in Spain."

A resident at Sean Heiss’s block of flats in St Marks Hill described seeing police arrive at his home last week.
