How did CCTV and scratches reveal the secret?
When the child did not return home till late night, the family lodged a missing complaint at the police station. Police examined CCTV footage, in which the child was seen going into an apartment. During the search, a blood stained jacket and blood stains were found on the roof.
The most shocking thing was that the accused Rehan himself kept roaming with the police in search of the child. But the police found scratch marks on his neck and hands. During interrogation, he made excuses, but broke down as soon as he became stricter.
