In the complaint, she stated that the suspect, identified as Ali Salman Alvi, called her from her sister's phone at 2pm saying that he was "ruined" and the victim, identified as Sadaf Zahra, had "done something", before hanging up.

She rushed to their home, along with her husband and mother, where they found the suspect standing at the main door while the rest of the doors had been locked from the inside, the FIR said.
