Both the Central Industrial Security Force (CISF) and local police force units, sources said, have launched special drives to identify and nab pickpockets with special focus on women.
Women officials of the CISF are being deployed in civil clothes to keep a check on the women who try to secretly whisk away valuables and cash of passengers in the Metro, the official said.
During January this year, the CISF also de-boarded 586 men from the Metro coaches exclusively meant for women.
Besides, 56 people were apprehended by the force so far this this year for the offence of walking on Metro tracks.
Seven instances of illegal arms being seized at the Metro entrance were also reported in the first three months of this year by the security force which has deployed close to 5,000 men and women to secure the network against any sabotage activity and security related threats.
