"He has been constantly changing his statements to Jammu police, so we cannot rely on him. Until we interrogate him, it will be difficult to even assume the family has been killed," said Himanshu Roy, JCP (crime), Mumbai Police.
"Jammu police are cooperating with us and on Saturday, we will be moving the local court seeking his custody," said Niket Kaushik, additional commissioner of police.

Earlier, the Jammu and Kashmir police confirmed the news that the Pakistani starlet along with her family was killed in Mumbai last year after following the revelation by Pervez Tak, who was taken into the police custody in connection with the case.
Tak revealed that the actress was possibly killed for her dubious links with the underworld.
Laila Khan and her family were last seen at a shop in Kishtwar town on May 29. The J&K police also recovered an abandoned car from a lake in Srinagar in which the family was travelling. Reports reveal that the vehicle was registered in the name of the Laila Khan's mother Saleena Patel, a Pakistani actress.
According to Tak's confession, Laila had married a close aide of underworld don Dawood Ibrahim. With her underworld links hogging the limelight, the Maharashtra Anti-Terrorist Squad (ATS) has been on the lookout for the star and her family.
Later, a complaint was lodged with the Mumbai police by Laila Khan's father, Nadir Shah Patel, who alleged that his daughter along with her mother Saleena Patel, her sister Azmina Patel, her stepfather Asif Sheikh and their family friend Pervez Iqbal Tak went missing after they left for Kashmir to attend a wedding.
