According to PTI, both the youth were in their 20s and were seen sporting the ISIS t-shirt and waving the Pakistani flag during a Muharram procession.
Eyewitness said that the youth were seen walking around wearing the ISIS t-shirt but no one stopped them. Finally the organisers of the procession sent him away.
"The duo were detained after the photos of the youth were published in the media. Deputy Superintendent of Police Rama Shankar Singh questioned them," Superintendent of Police Hemant Toppo said.
So far no FIR has been lodged in the case.
Police even picked up the man who was responsible for printing ISIS Pakistan on the t-shirts.
Jharkhand is not new to the presence of terror outfits. Of late, several sleeper cells of terror outfits like SIMI and Indian Mujahideen were unearthed.
