Turkish Cypriot business tycoon Asil Nadir has allegedly been assaulted in prison by his mentally unbalanced cellmate, English tabloid the Sun reported Feb. 17.

Nadir, nicknamed “the Sultan of Berkeley square,” is serving a 10-year prison sentence at Belmarsh high-security prison in South London, for stealing a total of 28.6 million pounds ($45 million) from Polly Peck International, which he built from a small textile firm into a conglomerate with interests in food, electronics and the leisure industry.

According to the Sun, Nadir has chided his cellmate for not showering and stinking of sweat, leading the unidentified inmate to allegedly assault Nadir. Authorities are concerned for the 71-year-old Nadir’s safety, the report said.
