Four accused in the case have been arrested so far including Sharma who surrendered today, police informed.
Officials further mentioned that the ones accused in the case so far are Nishant Sharma, Baidullah Khan and Samsula Khan.
Meanwhile, the chief judicial magistrate of Dibrugarh sent Sharma to police custody.
