Polygraphic tests conducted on Pandher, Koli

New Delhi, Jan 29: Investigation teams probing the Nithari serial killings today conducted 'polygraphic tests' on the two arrested accused for the second consecutice day.

The 'tests', being conducted on Moninder Singh Pandher and Surinder Koli, were to ''elicit the truth'' regarding the killings, said a senior CBI official.

''The tests are part of the interrogation process and were carried out throughout the day.'' These tests, being conducted at the CGO Complex headquarters of the central agency here, were also carried out yesterday on the two and were likely to continue tomorrow as well, the official added.

The two accused are in CBI custody since early this month.

Both are reportedly behind the alleged killing of more than 38 children who went missing in neighbouring Noida's Sector 31 Nithari village in the last nearly two years, besides several others.
