New Delhi: Over 200 people have been interrogated in links with the mysterious deaths of 11 members of a Bhatia family in north Delhi's Burari Sant nagar.

 According to sources the police are awaiting the final postmortem report even though initial findings suggested that the 11 died of hanging.  Worth mention here after receiving the report, the police will go for a psychological autopsy of the dead to ascertain what prompted them for replicating "badh Pooja", a banyan-tree like structure.

Even as the police are certain that it was a case of "mass suicide", the investigation process is still on.

On a related note, one of the deceased, 33-year-old Priyanka Bhatia's fiancé was interrogated again and he refused knowing anything about the family indulging in certain kinds of rites. He was interrogated for close to three hours on Monday, sources  informed.

During inquiry, police had also found that Priyanka had 'manglik dosh', which was main reason responsible for her not being able to find a match earlier.

Ten of the 11 members of the Bhatia family were recovered hanging from an iron-mesh in the ceilingon July 1, while the body of 77-year-old Narayan Devi, the head of the family, was lying on the floor in another room of the house.
