Police in Kasur deny they have been lax in investigating child abductions in the town. DNA samples have reportedly been taken from dozens of potential suspects, but no one has yet been arrested.

Zainab Ansari was last seen on her way to a religious recital when her body was found 2km from her home.
It was relatives of the missing girl, and not the authorities, who reportedly tracked down CCTV footage that showed Zainab being led by the hand down a road by an unknown man.
A police official described the situation as "very tense".
Police in Kasur have recorded 12 similar murders over the past two years, and believe at least five of the cases can be linked to the same person, the BBC reports.
