CHENNAI: Security at the Christian College Medical College Hospital (CMC) in Vellore was beefed up on Sunday following a death threat to Durai Dayanidhi Azhagiri, as reported by Maalai Malar.

Hospitals authorities said that an email claiming that the life of Durai who is being treated at CMC for the past few months, was under threat, was sent to the hospital's medical superintendent office.

The email prompted an immediate complaint to Vellore District Superintendent of Police (in-charge) Kiran Shruti. The cybercrime branch has launched an investigation into the matter.

Following the threat, to ensure Dayanidhi's safety, three plainclothes policemen, led by a sub-inspector, have been deployed at the hospital premises since Saturday evening.
