More than a month after the Nithari serial killings came to light, skeletal remains continue to surface in the area, with two more bones being recovered on Thursday.

The bones, portions of jaws, were discovered by the families of victims who have been holding protests in the area for the last three days.

The skeletal remains were handed over to the police, who later gave them to the CBI that is investigating the serial killings, a police official said.

"The bones are not necessarily human remains. But we have handed over the bones to the CBI for further investigations," the official said.

The demonstrating families found the bones in the silt dug out of the drain outside D-5, Sector 31, the residence of main accused Moninder Singh Pandher, by the investigators earlier while looking for human remains.

Meanwhile, the families of the missing children continued their demonstration in the area although the road leading to Nithari was cleared for normal traffic.
