Four low-intensity blasts rocked Pune on Wednesday evening, injuring one person.
The blasts took place within 40 minutes between 7.30 pm and 8.30 pm on the busy Junglee Maharaj Road with many restaurants and shops. Two more bombs were defused by the Anti-Terror Squad.
The injured person is being treated as suspect and questioned by the police. A terror angle cannot be ruled out as it appears to be a planned attack, Home Secretary RK Singh told NDTV. "Please stay calm...the government of India and Maharashtra will work towards cracking this," he added.
"The blasts were of low-intensity. I was supposed to be at the Tilak Theatre, very near to where one of the blasts took place. At this moment, I cannot say anything more. It is now a matter of inquiry," Sushil Kumar Shinde, who took over Home Ministry on Wednesday, told reporters.
The new Home Minster was scheduled to visit the city on Wednesday but cancelled due to other commitment.
Senior police officer Satyapal Singh told NDTV that explosion was caused by a device hidden in a dustbin at a branch of McDonald's while another went off near a popular theatre. "There have been four blasts and one person has been injured. The fourth blast took place in the dustbin of McDonalds," he added.
Maharashtra Chief Minister Prithviraj Chavan called for an emergency meeting with the officials to discuss security measures in Mumbai following the blasts. All the major cities in the country have also been put on high alert.
