New Delhi, Jan 15 (ANI): Railway Minister Suresh Prabhu on Thursday called for seamless policing to ensure security and safety of the passengers. The minister, addressing the Conference of Director Generals of Police (DGP) of all states on railway security, said with the increase in crimes, it is inevitable that railways will also be its victim. Social, political and economic factors also contribute to the crime rate going up; and unemployment, regional disparities and growing ambitions not being fulfilled also contribute to it, Prabhu added. Inviting the officers to device joint strategy to deal with crimes, especially on running trains, the minister said as law-enforcers there is a challenge as policing in railways is a difficult task. Also present at the conference was Home Minister Rajnath Singh, who said Indian railways is a developmental as well as a strategic asset. Singh assured the DGPs that his ministry would cooperate and coordinate with the ministry of railways to ensure safety and security.
