Minister of State for Home R P N Singh said the Home Ministry takes all reports of information leaks with utmost seriousness.
"We have taken action in similar cases in the past with an iron fist. If there is anything in this case, the Home Ministry will take action," he told reporters here.
Singh was reacting to reports that a major-rank officer of NSG talked unauthorisedly to Pakistani intelligence officials regarding developments about the recent blasts in Hyderabad.
Ranjan, however, said there was nothing alarming in the incident and nothing vital leaked during the brief talk between the NSG officer and the Pakistani, who is suspected to be an ISI agent.
