Former Mumbai Police commissioner Param Bir Singh on Monday took charge as the Director General (DG) of Maharashtra Home Guard, a police official said. Singh reached the Home Guard office in south Mumbai around noon but avoided speaking to media persons.

Under flak for "mishandling" of the bomb scare outside Mukesh Ambani's residence here, the Maharashtra government on March 17 transferred Singh from the post and appointed senior IPS officer Hemant Nagrale, who was holding additional charge of Maharashtra DGP, as the new commissioner of Mumbai Police.
