Later, around 27 of these inmates allegedly inflicted self -injuries on themselves in a bid to show their displeasure.
The incident happened on November 10 at the launch of second season of 'Tihar Idol', a singing talent show that the authorities of the high-security jail first organised in 2012 on the lines of famed 'Indian Idol'.
Playback singer Sonu Nigam had launched the show and other noted artists including Raja Hassan, Nandini Dev and actress Akriti Bharti and Sonu's father Agam Nigam had also performed at the show.
The jail administration, however, got wind of their plan and blacklisted them. They also not allowed the prisoners to attend the function and kept them confined to their wards.
The incident took place in the ward number 8, around 9 PM on the night of November 10.
"On the function night, the inmates who were not allowed to attend the function were found injured in their ward. All of them were given medical treatment and police was informed," a senior jail official told PTI.
According to sources, blades and other sharp objects were used in the incident which was later recovered during searches in the ward.
"We have been successful in preventing a big threat. Our security officers had prior suspicion that something big was being planned. 2000 people, including celebrities were out there to attend and enjoy the function here. Keeping their security in mind, a certain group of inmates were not allowed to attend the function," the official said.
On the next day, when these miscreants were being transferred to different wards to break their group, around 24-25 inmates of the ward number two also inflicted injuries on themselves in protest and to pressurise the jail administration.
