Days after senior Congress leader Salman Khurshid's house in Uttarakhand's Nainital was vandalised, four people were arrested on Thursday in connection with the attack.

Khurshid's house at Satkol, about 15 km from Nainital, was vandalised on November 15 amid the ongoing controversy over his book "Sunrise Over Ayodhaya: Nationhood In Our Times" in which he draws a comparison between Hindutva and terror outfits like ISIS.
