Talal al-Rouki with his pressure cooker
A Saudi student was surrounded by armed FBI agents in the United States overnight after neighbours saw him with a pressure cooker and called police.
Talal al-Rouki, living in Michigan, had been cooking a rice dish
and was carrying it to a friend's house, English newspaper Daily Mail said.
When agents who surrounded his apartment asked a "nervous" al-Rouki if they could come in and question him, all they found was kabsah - a traditional Saudi rice dish.
US authorities and residents have become increasingly nervous about home-made pressure-cooker devices after the Boston bombers used one to make an explosive.
"They asked me about my major, when I arrived in the US and what I do in my spare time" Mr al Rouki told the Saudi newspaper Oukaz.
An FBI agent said: "You need to be more careful moving around with such things sir."
Officers said that two days earlier a woman had seen him walking out of his apartment carrying the pressure cooker pot, which was described as "bullet coloured."
