Dehra Dun: A letter purportedly written by Pakistan-based Lashkar-e-Toiba outfit to Haridwar Railway station superintendent threatening to blow up vital installations across Uttarakhand has triggered a security alert in the state.

The hand written letter by LeT was sent through post in the name of Haridwar Railway station superintendent Samarendre Goswami, who after reading the contents of the letter informed railway police authorities.

In the letter signed by one Karim Ansari, who claimed to be the self-styled area commander of the terrorist outfit, LeT threatened to attack Haridwar bus stand, Rishikesh railway station, cinema halls, religious shrines and other crowded places across Uttarakhand besides Haridwar railway station and Har-Ki-Pauri, police officials today said.

The organisation has threatened to blow up the places on April 15.

"We have beefed up security at all vital installations all over Uttarakhand following the recovery of LeT's letter," an official said.

Police have launched investigation to verify the contents of the letter and are trying to know the place from where the inland letter was posted from.
