Mumbai: The Thane police, yet to ascertain the motive behind the gruesome act of 35 year-old Hasnain Warekar who murdered 14 members of his family including his parents, wife and two children and then committed suicide, today said they would also seek the help of psychiatrists.

The macabre killings took place in the early hours of Sunday in Kasarwadvali area of neighbouring Thane city. "Until we record the statement of the lone survivor Subiya Barmar (one of Hasnain's sisters) we cannot say anything about his motive," said the joint commissioner of police Ashutosh Dumbre at a press conference in Thane today.
