Panchkula police said today that besides Aditya, three other key accused were evading arrest.
"We have recommended to the government that the reward money in case of Aditya Insan be doubled from Rs one lakh. As regards the other three accused, the reward money leading to their arrest will remain Rs 50,000. The informer's name will be kept secret," Panchkula DCP Manbir Singh said over the phone.
In September, a lookout notice was issued against Aditya Insan, who was a spokesman of the Dera then.
Manbir Singh said that Haryana police had also pasted posters of the four wanted persons at several locations including five in Uttar Pradesh.
