The Chandigarh police on Wednesday arrested Vikas Barala (23), the son of Haryana BJP chief Subhash Barala, and his friend Ashish Kumar over charges of kidnapping and stalking an IAS officer’s daughter Varnika Kundu.

The two, who will be produced in court on Thursday, arrived at the police station in Chandigarh’s Sector 26 five days after they were charged with kidnapping and stalking.

“Detailed interrogation of both (Ashish and Vikas) took place; two charges to be pressed against them,” says Chandigarh DGP Tajender Singh Luthra.

Earlier Varnika had posted on Facebook a harrowing account of being chased for several kilometres by Vikas and his friend Ashish on Friday after midnight. The 29-year-old DJ said they blocked her car, banged on her window and even tried to force open her door. The chase was caught on six CCTVs, the footage showing a white SUV racing after Ms Kundu's black sedan.

A police patrol team finally responded to the frantic SOS calls of Ms Kundu. But Vikas and Ashish were let off within hours of their arrest, because they were only charged with stalking and drink driving, which are bailable. The two had refused to give their blood and urine samples the night they were arrested.

After Ms Kundu's Facebook post went viral and led to massive public outrage, the spotlight was on the police, which was accused of trying to dilute the case under pressure from the state's ruling BJP. The opposition Congress has accused the Centre and state governments of pressuring the police to dilute the probe, while the BJP has stood behind Barala ruling out his resignation.
