"This happened only two months back, when I was extending my full support to Bishop Franco Mullakal, who was arrested in a sex abuse case of a nun last year," George told media.
"The reason why I kept mum then was because he threatened to finish off one of my two sons," said the seven time legislator, adding that he did instantly inform chief minister Pinarayi Vijayan and State police chief Loknath Behera.
"While the first caller had identified himself as Pujari, during the second call that he received from the same number, the caller was speaking in Malayalam and said that he has been instructed by the mafia don," George said.
"A subsequent police probe revealed the call came from South Africa and the caller was indeed Pujari", said the Poonjar MLA.
"On both occasions when he abused me, I gave it back to him. And since then our security has been heightened, especially that of my younger son," he added.
