A woman Railway Police officer probing the Samjhauta Express blast case on Wednesday alleged she had received a telephone call threatening her with dire consequences if she persisted with the investigations.
Superintendent of Police Railways (Haryana) Bharti Arora told PTI that the caller identified himself as an activist of an extremist outfit and told her to slow down the pace of the probe.
Otherwise, she would have to face dire consequences, the caller warned her, the woman police officer said.
Arora said she had received the call on the landline at her office on January 16 and a day after, she reported the matter to SP (Ambala) Y Puran Kumar.
Kumar was looking into the matter, she said adding she had also summoned a meeting of GRP officers in this regard.
A case had been registered in connection with the alleged threatening call, police said.
In the past two years, some six anonymous letters had been received by the Railways threatening to blow up Ambala Cantt, Ludhiana, Chandigarh and some other stations if the authorities persisted with the probe.
Sixty-eight people, mostly Pakistani civilians, were killed in the Samjhauta Express bombings and the ensuing blaze near Panipat on February 18, 2007.
