Indian investigators have named the man who they claim was driving the car that blew up last Monday near the landmark Red Fort monument in capital Delhi.
The National Investigation Agency (NIA), India's counter-terrorism agency, named Umar Un Nabi as the "alleged suicide bomber" in the incident that killed 10 and injured 32 others.
A doctor from Indian-administered Kashmir, Umar was working as an assistant professor in the general medicine department at Al-Falah University in Faridabad, a Delhi suburb, the NIA said, adding that it had established the driver's identity forensically.
Umar's father and sister-in-law told the BBC that they "can't and don't know" anything about it.
The agency named Umar on Sunday after it said it had arrested a man - also a resident of Indian-administered Kashmir - in whose name the car used in the blast was allegedly registered.
