The Mumbai hub of National Security Guards (NSG) would become operational on Tuesday, nearly seven months after the 26/11 Mumbai terror attacks.

According to a statement, there was a need to have presence of NSG in other metros following the terror attack in Mumbai and hence four regional hubs were sanctioned and are being raised and put into action at Mumbai, Chennai, Hyderabad, and Kolkata

While the Mumbai regional hub becomes operational June 30, the hubs at Chennai, Hyderabad and Kolkata will become operational on July 1.

The government has also sanctioned two NSG regional centres to be stationed at Kolkata and Hyderabad. The existing hubs at Kolkata and Hyderabad will subsequently be merged with the regional centres.

The new NSG hubs have been established at Marol (23 acres) in Mumbai, Nedunkundram (85 acres) in Chennai, Trimulghery (22 acres) in Hyderabad and Badu (20 acres) in Kolkata.

Pre-fabricated and permanent structures are being constructed to station NSG commandos at these locations. The National Buildings Construction Corporation Ltd (NBCC) has been assigned the construction work.

After the Mumbai terror attacks, the cabinet had approved setting up of NSG hubs in the metropolitan cities to quickly mobilise commandos in case of a terrorist strike. With the establishment of the hubs, NGS would be able to act in quick time in case of a terror attack.
