"We have increased security at places where Headley conducted a recce," Chavan told reporters after reviewing the state security situation. We have beefed up security at airport and railway stations, he added.
Asked who was the primary suspect in the Pune blast, Chavan said, "As long as full information is not available," he would not comment.
"That terrorists are involved (in the blast) is almost certain," he said.
According to information with the police, Headly had conducted a recce of Chabad House, a Jewish prayer house, and Osho Ashram, he said.
Asked if a security advisory had been issued by central agencies ahead of the attack, Chavan said, "I will check with my people."
The chief minister denied there was a lack of coordination between the state and central intelligence agencies. "There is proper information-sharing," he said.
On the diversion of police force for bandobast duty during the Shiv Sena's agitation against Shah Rukh Khan's film My Name is Khan, Chavan said, "Security of the common man is more important than that of theatres."
