A crude bomb exploded on the outskirts of the state capital here Sunday afternoon but no one was injured. Four other bombs were recovered in the area and defused.
"When a man was setting fire to some garbage at Abhoynagar (on the city's outskirts), a handmade bomb exploded. Police subsequently recovered four more crude bombs from the garbage and defused them at once," police spokesman Bharat Debbarma told reporters.
Police were yet to detain any one in connection with the incident.
Senior police officials along with Tripura State Rifles troopers launched a manhunt to nab the culprits behind the occurrence.
