Police on Tuesday recovered more skeletal remains in Nithari village in Noida, the site of the gruesome serial killings of children and women.

A bone was found in the drain behind the D-5 residence of Mohinder Singh Pandher, the suspect in the killings, who is being subjected to narco-analysis tests in Gandhinagar.

The bone was found by villagers who informed the police.
