A Bangladeshi who was a former associate professor at a Japanese university is among the 10 suspects sought by Bangladesh police following this month's terror attack in Dhaka, sources said.

Mohammad Saifullah Ozaki, who was born in Bangladesh, taught at Ritsumeikan University in Kyoto Prefecture, but has been missing since he left Japan last year for Europe with his family, the sources said Wednesday. His wife is Japanese.

Ozaki, who had started teaching business administration at the College of International Relations in April 2015, has been absent without permission since January, the university said. He was fired in March.
