Police said that a Chinese-made hand grenade wrapped in a polythene bag was found at the entry gate of the residence of Yumnam Rupachandra, the News Editor-in-Chief of local cable channel Impact TV, at Singjamei area in the district on December 14 that was subsequently defused by bomb disposal squad personnel.
In yesterday's meeting, Y Rupachandra said he had received a phone call on the night of December 14 at his office.
He said that the unidentified caller informed him about planting a bomb at his residential gate as a warning to not cover their organisational press release issued earlier.
