Former teacher Martyn Latchman, 38, became unwell during the preparatory phase of £1,500 procedure

A British man has died after undergoing a hair transplant procedure in Istanbul.

Martyn Latchman, 38, from Milton Keynes, who left a 16-year career in teaching last year to become a defence contractor, died last week after becoming unwell during the preparatory phase of the £1,500 procedure.

The clinic involved, Dr Cinik in the Besikitas area of the city, whose former clients include the ex-England and Manchester United footballer Rio Ferdinand, said it was not known why Latchman fell ill.

He was transferred to an intensive care ward in a nearby hospital but died later that day, the clinic confirmed. Turkish media said police had launched an investigation.
