Just minutes before firing at the protesters marching from Jamia Millia Islamia to Rajghat against the controversial Citizenship (Amendment) Act (CAA) on Thursday, the teenager had gone live from his Facebook profile named 'Rambhakt Gopal'.

His Facebook profile showed that he is a 19-year-old resident of Jewar in Uttar Pradesh's Greater Noida but police is yet to confirm his age. On Thursday, around 11 am, the accused Gopal wrote his first post in which he mentioned "All brothers are requested to see me first," Later, he went live on facebook and showed the students gathering outside Jamia University to march towards Rajghat.

In most of his facebook live footages, the accused can be seen walking around the venue of the protest looking around furtively for a target. While in his previous posts, he wrote that he had pre-planned the attack and was prepared for the consequences.

His posts read foul and abusive language and he wrote that "Please take care of my family" "Im the only Hindu here" referring to the protest by Muslims. He even told people not to call him.

In one of his posts, he has taken a person's name and stated that this revenge is for him. "I'm on my last journey, I want to be draped in saffron colour and want people to chant "Jai Sri Ram"," he said in Facebook post.

His last post before going facebook live again was "Shaheen Bagh, Game over," referring to the massive protest led by women in South Delhi's Shaheen Bagh area since 15 December.

One of the videos, which went viral on social media, show the teenager brandishing the gun while shouting 'Yeh lo Azadi' (here's your freedom). Later, he fired at the protesters before being over powered by the people around him and arrested by police.

According to police, a Jamia student sustained bullet injury on his left hand due to the firing by the teenager.
