The railway police in Haridwar has received a letter purportedly sent by Pakistan-based terror group Lashkar-e-Toiba threatening to attack top government functionaries and vital installations in Uttarakhand during the festival season, police said on Thursday.
The letter was received on Wednesday by the office of the Haridwar Railway Superintendent, which had also got several such letters in the past.
A spokesman of Haridwar Police said efforts were on to trace one Karim Ansari, who is said to have written the letter.
The terrorist outfit had earlier threatened to attack vital installations on the occasion of Independence Day.
