The Gujarat Forensic Department is all set to conduct detailed scientific tests on the two Noida-based alleged serial killers.
They will be brought to the state on Thursday by Uttar Pradesh police, a senior forensic official said.
Moninder Singh Pandher and his servant Surendra, arrested for allegedly killing several children in Noida, would undergo narco-analysis, brain finger printing and polygraph tests at the Directorate of Forensic Sciences, the official said.
The two are expected to undergo these tests at the special operation theatre at the DFS.
"Our methods are so scientific and comprehensive that we are quite sure the accused will give all the details the investigating agency wants," the DFS official said.
The OT also has a chamber where the entire proceedings are videotaped and a glass window separates the room from a waiting room where the kin or advocate of the accused can wait and watch, the official said.
