Albert Douglas, 61, was trying to connect to his family from a Al Barsha prison phone when the inmate attacked him from behind, his son said. The grandfather is currently in prison in the UAE.

A millionaire British businessman fears he will die in prison in Dubai after being jailed over business debts run up by his son.
Albert Douglas, 60, has fought a £1m legal battle to prove he was not liable for money owed by his son Wolfgang s business.
And he became so desperate at one point he dramatically attempted to escape the country into neighbouring Oman - but was arrested as he tried to climb a border fence and hauled off to prison.
The grandfather has since spent two months in a hell hole jail where he claimed he was beaten by guards when he asked for his heart medication.
