Mock security drill at Reserve Bank of India headquarters

Mumbai, Apr 11 Security organizations Thursday carried out a mock drill at the Reserve Bank of India's (RBI) headquarters here, which included a helicopter hovering over the 25-story working in south Mumbai.

A video shot from the street below shows a helicopter coming over the RBI building's porch and a couple of security men slithering down.

As part of the mock drill, the security establishment created a "hostage situation" where people must be cleared from a specific floor in the RBI building, sources said.

The entire operation, involving multiple agencies, was planned to the last detail, they said.

There are different kinds of security and fire drills that are directed all the time and this was a particular one which involved the use of helicopters.

It can be reviewed that during the November 2008 terror attacks, commandos from the National Security Guard (NSG) had crawled down on the Chhabad House, one of the three sites of assault, and killed the terrorists holed in.

As part of Thursday's drill, a chopper hovered close to the roof of the RBI working in the high security area, taking everyone by surprise.

A senior police official said it was a security drill designed keeping in mind a few possible scenarios.

RBI sources said it was a "mock drill" did by the national bank's in-house security department with the assistance from other agencies.
