A British banker has been found dead and tied up at his home in an upmarket region of South Africa.

The body of James Starkey, 36, was found at the Raphael Penthouse Suites in Sandton, north of Johannesburg, on October 8.

A worried friend had raised the alarm. Mr Starkey, of Woolwich, south-east London, had been working in South Africa for two months.

Colleagues at Catalyst Development, the London-based financial services consultancy where Mr Starkey worked, have been "shaken and shocked" by the death of their friend.
