Boston arrest teenager 'doesn’t go to the mosque', claims father

Former teachers of one of the students from Kazakhstan arrested in connection with the Boston Marathon bombings have described him as an easygoing teenager who distinguished himself mainly by his failing grades in maths and science.

Dias Kadyrbayev was a university friend of bombing suspect Dzhokhar Tsarnaev. He and another 19-year-old student from oil-rich Kazakhstan, Azamat Tazhayakov, have been charged with trying to destroy evidence by allegedly disposing of a backpack and laptop computer taken from Tsarnaev’s dorm room after learning he was a suspect in the attack.
