Additional commissioner of police (south) Aishwarya Singh said, "The accused, a resident of the same apartment complex, has been arrested." Police said they received information around 9.30pm on Friday from a private hospital about three men admitted to the facility with stab wounds. Two of the victims, Rakesh Sood, 62, and his son Karan Sood, 27, were declared dead. "Their relative, Rahul, is under treatment.
