New Delhi [India], July 6 (ANI): The Crime Branch of Delhi Police on Friday interrogated a 'tantrik' (occultist), named Geeta Maa, in connection with the deaths of 11 members of a family in the city's Burari area on Sunday.

As many as 130 people have been interrogated till now regarding the Burari deaths.

The police also questioned the family's neighbours, relatives, and fiance of Priyanka - one of the 11 members of the family.
