The letter addressed to her was sent by post and received by the party office “Kamalalayam,” on June 6.
It was, however, opened only today.
“A sheet of paper inside the envelope was laced with a type of explosive chemical, usually found in firecrackers and a probe is on,” a senior police officer told PTI.
Though no explicit words were used about carrying out a “bomb threat” to the BJP office or the state unit chief, a wick was attached to the explosive laced paper and it is perceived to “symbolise a bomb threat,” the officer said.
Tamilisai said the letter had used “filthy, foul language,” which no one could read.
“The letter received at party office appears to be a copy of a letter I got at my residence. It threatens me with dire consequences,” she told PTI, adding the letter received at her residence was immediately handed over to Virugambakkam police station.
Recently, police had stepped up security to Tamilisai after she complained of having received a threat call over phone.
