Meanwhile, a police official said they spoke to the family members of Rehana, including her brother, but they did not suspect anyone behind the crime.
A police source also said they were examining the phone call details of seven persons, including family members of the deceased, to get a breakthrough in the case.

"We are probing the case from all possible angles including property dispute, personal enmity, robbery and revenge killing. A flat worth Rs 70 lakh could also be a reason of dispute between Rehana and Aleem. The Rs 20 lakh that were allegedly missing from the house could be a trick to mislead investigators," said a senior police official.

The official rubbished media reports that Rehana had filed a case of domestic violence against Aleem with the Woman Cell of Krishna Nagar Police Station.
The official said that before her murder, Rehana had last spoken to her sister Farzana and she spoke about family affairs and nothing serious was discussed, police said.
