London, September 15 : A British security expert has revealed that he has broken safes for Al-Q''aeda head Osama bin Laden and Ugandan dictator Idi Amin, whom he describes as "friendly" and “fun” respectively.

Arthur Riding, 59, said that he met Laden dozens of times while working in the Middle East.

He said that he had installed bulletproof glass at Laden''s home in Saudi Arabia.

He even revealed that he once opened a safe for the terror chief.

"You could talk to him and he was reasonably friendly. There was no clue that he would go on to do what he has done," the Telegraph quoted the father-of-one from Birmingham as saying.
