One person was injured in a bomb blast near the gate of the Assam Rifles office in the Manipur capital on Wednesday, police said.
Thokchom Kumar, a civilian, was sitting in a hotel when the blast occurred in the Chingarel area. His condition is stated to be stable.
"Preliminary investigation indicates that rebels could have triggered the improvised explosive device blast from a distance," Inspector General of Police Clay Khongsai told IANS.
No one has been arrested so far, but a manhunt is on to nab the rebels, he added.
