Suspected militants triggered a blast near the Raj Bhavan here Saturday, police said, adding there were no reports of any injury or any major damage.
Police said that the blast took place in the evening at the empty Governor' Road - a small lane behind the Raj Bhavan and outside the compound wall of the governor's residence.
"Preliminary investigation shows it to be an IED," said a senior police official.
No outfit has, however, claimed responsibility so far for the blast.
