Some of the cases were dismissed as complainants became disinterested to continue trial. Other cases were for intimidation and threat terrorism, extortion, toll collection and repression, police sources said.

The home ministry has asked for all papers regarding sensational cases against Sarwar, according to BMP Commissioner Khan Sayed Hasan.

The cases would be reinvestigated if complainants want to revive those or if is found that those were dismissed due to faulty investigation or political pressure, the BMP Commissioner said.
