"Police arrested Vineet Kumar, IT head of Dera Sacha Sauda, yesterday and seized 60 hard disks on the information provided by the accused," Sirsa Superintendent of Police Ashwin Shenvi said.
During investigations, it came to light that the Dera authorities had changed several hard disks before the search operation at its headquarters in Sirsa, he said.
He said that the computers of the Dera were tampered with and hard disks removed or altered before the sect's headquarters at Sirsa were searched under the supervision of a commissioner appointed by the Punjab and Haryana High Court.
Mr Kumar was summoned by police for questioning at Sirsa yesterday after he was evasive in his replies on the computer cell of the Dera, he said.
Meanwhile, police also arrested Harmel Singh, the driver of Lexus SUV car belonging to the Dera that was torched near Phoolkan village on August 28, the day the sect chief was sentenced to 20 years of imprisonment for rape, he said.
Mr Singh was arrested from Rajasthan, the officer said adding that he had been booked for causing damage and destroying evidence.
Police also arrested Bhag Singh, a member of the Dera, from Ambala today and seized Rs 14 lakh from him.
Secret tunnels, including one which linked jailed Ram Rahim's plush residence with female disciples' hostel, an empty box of AK-47 cartridges, an illegal firecracker factory were detected during the Dera's serach recently.
The sanitisation exercise of the Dera was conducted two weeks after Ram Rahim was convicted and jailed by a special CBI court for raping two disciples.
