Surendra displaying violent tendencies, kept handcuffed: CBI

New Delhi, Jan 19 (UNI) Prime accused in the Nithari serial killings Surendra Koli displays ''violent tendencies'' even while in custody and was being kept hand-cuffed, even as the investigation team studied the forensic tests already conducted on the skeletal remains found from the Noida site.

Despite being hand-cuffed Surendra often bursts into a violent flurry spewing words which shows his violent tendencies, according to CBI sources carrying out investigations into the Noida Sector 31 grisly killings.

''Surendra says he still feels like killing and eating people', which actually displays his deranged mentality and a psychopathic tendency,'' they said, adding that because of this mental frame, he has been kept handcuffed, said the official.

Investigators have kept both the arrested accused -- Surendra and Moninder Singh Pandher -- separately while carrying out their interrogation.

''This has been done to avoid any sort of 'connivance' between the two.'' Also, their room were being kept free of any dangerous objects or materials with which they could attempt suicide, he said.

The official also informed that forensic tests on the 'biomaterials' collected were over and the CBI team was studying the findings before it could derive any conclusions. ''This will take another six to seven days.'' Also, on Surendra's instance, the bag of Deepika alias Payal, whose mobile led to the unravelling of the serial killings, was also recovered from beneath his bed, the official added.

Last night the police had found an axe and polythene bags, resembling the type found containing skeletal remains dumped by the accused, from the D-5 killer house.

Meanwhile, the CBI team today raided the Faridabad 'den' of Neelam -- the 46-year-old 'madam' and 'supplier' of Deepika alias Payal.

It also questioned about ten policemen deployed at Nithari 'chowki' between 2004 (ever since the children started disappearing from Nithari village) and December last year in connection with the case.

Yesterday, the Noida Police submitted all the materials it had collected during its searches to the CBI for investigations.
