Police have registered a case against him under relevant sections of the Indian Penal Code (IPC) and the Arms Act. His four-day police custody ended on Saturday, officials said.
On Friday, the pistol that he pointed at a police official during the communal violence was recovered from his house.
After opening fire, he kept the pistol at home and fled from the city in a car, police said. In the viral video, Pathan, a resident of northeast Delhi's Ghonda, could be seen pointing his pistol at the policeman on the Jaffrabad-Maujpur road on February 24.
Police said after seeing himself on news channels following the incident, Pathan changed his clothes and fled to Punjab. He then moved to Bareilly in UP before hiding at a friend's house in Shamli in the state.
The good quality semi-automatic pistol used by Pathan was bought from Munger in Bihar, according to police. A college dropout, Pathan was interested in body building and modelling. He used to make TikTok videos. He owns a shop and a socks manufacturing factory in Ghonda.
