The office of the TNA Northern Provincial Council (NPC) member, Ananthy Sasitharan is under military surveillance, locals sources said.
"The army is involved in unusual patrol activities in front of my office in Sulipuram and military intelligence are monitoring the office from shops opposite," Sasitharan told the Uthayan.
The heightened military activity comes amid the Tamil nation's annual remembrance day commemoration on November 27 - Maaveerar Naal.
Earlier in the day, trees were planted in the North-East in memory of fallen LTTE cadre.
The Sri Lankan government has attempted to stifle any commemoration of Maaveerar Naal since the end of the military conflict, with extensive military deployment across the North-East, and particularly in Jaffna, at this time of year.
"On this special day, amid military occupation, we plant trees in memory of Maaveerar," Sasitharan tweeted.
