Security has been beefed up in jails where Gogi and Tillu gang members are lodged, officials said Saturday, a day after a bloody shootout in the Rohini courtroom left three gangsters dead.

Jailed gangster Jitendra Gogi and his two assailants posing as lawyers were killed inside the crowded Rohini courtroom Friday in a dramatic shootout that also saw the police fire bullets in retaliation.
