Militant outfit Kangleipak Communist Party - Military Council (KCP-MC) on Saturday claimed responsibility for planting the car bomb at Raj Bhavan in Imphal.
In a statement issued by the outfit, its self-styled military affairs secretary Lanheiba Meitei said the car bomb was planted on Friday by its 5th unit special demo team.
It also claimed that the outfit can breach the security of VIP areas and plant bombs there.
According to official sources, some persons who arrived there in two cars, posed as civilians and entered the Raj Bhavan complex on the pretext of submitting a memorandum to Governor Gurbachan Jagat.
While the car with 25 kg of explosives, three hand grenades and two mobile handsets was left behind Raj Bhavan, they left the complex by the second car, the sources said.
The explosives and grenades were later defused by bomb experts.
