Rahman, yang dikabarkan menghimpun kekayaan dalam jumlah besar melalui cara-cara yang patut dipertanyakan, ditangkap oleh pasukan keamanan pekan lalu dan diinterogasi oleh badan-badan intelijen pemerintah.
Rahman, who had reportedly amassed huge wealth through questionable means, was arrested by security forces last week and was under interrogation by government intelligence agencies.
