According to ATS, Yasin hails from Bhatkal in Karnataka,

Tahaseen is from Samastipur in Bihar while Asadullah is from Azamgarh in Uttar Pradesh. The ATS mentioned Waqas's age, description of his physical appearance, but did not disclose as to which place he hails from, stating that they do not have his exact details with them. "After consulting with all the security agencies, the decision to make public the faces of the four accused has been taken," Maria said. Explaining the modus operandi of the accused, Maria said the accused used to focus on areas in which mostly students resided. They would then take a property on rent in such areas by disguising as students. "There were instances when we had shown the photos of these accused to people during the investigation, who said that they had seen them a few days before. So we decided that if we release their photographs, it will become easier for us to trace them," Maria added. The posters would be circulated across India and could be seen at important locations, railway stations, police stations, security agencies, bus stops, educational institutes and others.
