Stones were thrown at the house of Ananthy Sasitharan, the TNA's popular Northern Provincial Councillor by unidentified persons during the early hours of Tuesday morning local time.
"I was sleeping at my house in Vadakkamparai, Chullipuram with my three daughters and a lady who stays with us, when I heard stones smashing against the house at around 1.30am," Sasitharan told the Tamil Guardian shortly after the incident.
"I got up and switched on the light and then they ran away," she said, adding that she had reported the incident to the police and the NPC chairman C. V. K. Sivagnanam via telephone.
The house in Vadakkamparai was previously attacked ahead of the Northern Provincial Council election in 2013.
The incident has occurred just days before Sri Lanka's presidential election on January 8.
Sasitharan said last week that she would not be voting for either candidate as both are responsible for the mass killing of the Tamil people and neither had pledged to address Tamil concerns.
Her refusal to accept the TNA's decision to openly endorse the common opposition's presidential candidate, Maithripala Sirisena however, has led to criticism from within the party's senior leadership.
