The Railway Headquarter in New Delhi has received a letter purportedly written by Maoists threatening to blow up Rail Bhawan along with some other vital railway establishments in Delhi, prompting authorities to step up security measures.
"A threatening letter, addressed to Chairman Railway Board (CRB), was received a couple of days back," a source in the Railway Ministry said on Friday.
The letter, claimed to have been written by Maoists, threatened that vital rail establishments, like the Rail Bhawan which is located next to Parliament and the Baroda House situated near India Gate, would be blown up, the source said.
While the letter is being examined for its authenticity, "precautionary measures" have been taken at these establishments, the source said.
A top official of the Railway Protection Force (RPF), which is responsible for security of railway properties, said Delhi Police has been informed about the letter and "necessary measures" were being taken.
He did not rule out the letter being a hoax.
Maoists have been off and on targeting railway property, like trains and tracks, in various states including Bihar, Jharkhand and West Bengal.
