Delhi and its surrounding cities have been on high alert, with police cracking down on illegal arms sale, since the November 10 blast near the iconic Red Fort. A high-intensity explosion ripped through a Hyundai i20 car at a traffic signal near the monument, killing at least 15 people.

Police have filed a case and launched an investigation into the incident. This is the latest case of student suicide after a number of such incidents have been reported in recent weeks. On Tuesday, a Class 10 student at a school in Delhi died by suicide after jumping from an elevated metro station.

Earlier this month, police arrested Dr. Muzammil Shakeel Ganaie and Dr. Shaheen Sayeed — employed at Faridabad-based Al-Falah University — and recovered thousands of kilograms of explosives-making material from the city near Delhi.
