The accused were identified as Manjeet (38), husband of the deceased, his girlfriend Angel Gupta alias Shashi Prabha (26) and Rajeev (40), they added.

Manjeet was in a relationship with Angel and his wife, Sunita, objected to it, so they conspired to eliminate her, Deputy Commissioner of Police (Rohini) Rajneesh Gupta said. Sunita was shot dead on Monday morning by unknown assailants while she was on the way to her school.
