Lamka, September 14: A Chinese hand grenade exploded on the stairs of Singngat MLA T Hangkhanpao's private residence here today, after some miscreants apparently in an attempt to intimidate him lobbed it from outside the campus.

"I had just uttered my morning prayers on bed when I heard something buzzing outside, but before I could step off from my bed, a big bang shook the entire building," sister-in-law of the MLA said.

All six window panes of the sitting room and many flower pots were shattered by the impact of the explosion, but no one was injured as the incident occurred at 5:30 am, when all six occupants were still in bed.

Police personnel who rushed to the site and collected evidence said that a Chinese made hand grenade was used in the attack.

"It could be an attempt to intimidate the MLA", a source said on condition of anonymity.

According to the in-law, Hangkhanpao was in town yesterday for a night-haul but changed his initial plan due to 'law and order problem', and returned to Imphal later in the day.

The real intention of the attackers remain a mystery as family members of the MLA have refused comment on the incident.

Zomi Students' Federation meanwhile has questioned the motive behind the attack and condemned it in the strongest term.

It must not be repeated, said the student body and urged the Government to be vigilant to avert any recurrences.
