Security at vital installations and residences of senior government functionaries in the Capital was stepped up in the wake of a series of low-intensity blasts in Pune on Wednesday.

The security personnel deployed at the 7 Race Course Road residence of Prime Minister Manmohan Singh were alerted and the entire area surrounding the bungalow barricaded soon after the blasts, which obstructed smooth vehicular flow.

A high alert was sounded in the city and all the police stations besides special units instructed to keep a watch on any suspicious activity. Extra security personnel were also deployed in and around Metro stations, particularly those located near vital installations like Parliament and railway stations.

“Bomb detection and disposal squads are on stand-by. All emergency services have been activated to meet any contingency,” said an officer.
