A 23-year-old unemployed youth was taken into custody after he reportedly threatened through email to kill Tamil Nadu Chief Minister M Karunanidhi and his family, police said in Chennai.
Police sources claimed that the accused Suresh Kumar had demanded that the engineering syllabus of the Anna University be scrapped as there was "an inherent flaw in the syllabus created by the University six years ago".
"Failure to comply with this request will result in the entire family of the chief minister being annihilated," the message had reportedly said.
Upon its receipt at the secretariat in Fort St George in Chennai on Wednesday, the city police's cyber crime wing swung into action and traced the message's origin to a cyber café in Tiruchirappalli, 300 kms south west of Chennai.
A police team led by K Sudhakar, assistant commissioner of police - cyber crime, travelled to the temple town, traced and apprehended Kumar on Wednesday.
Police indicated that Kumar had found the syllabus "too tough" during his campus life between 2001 and 2005. He is yet to get a graduation certificate as he has failed to pass in three papers.
"I thought that the chief minister would relent after receiving the email and that would get me relief. I have not been able to get a job all these years. This frustrated me," Kumar is said to have told the police.
He was produced before a local magistrate in Chennai and remanded in judicial custody.
