New Delhi, Jan 20: Surendra Koli, one of the two accused in the Nithari serial killings, shocked interrogators from the CBI when he told them he had again developed a "desire" to murder someone.
Koli, who is being questioned along with co-accused Moninder Singh Pandher at an undisclosed location by the CBI, said he had the desire to "kill someone", senior officials involved in the probe said.
The officials said instructions had been given that no one should question Koli without taking "proper precautions", including having armed guards present during the interrogation.
The CBI is taking the help of psychiatrists while questioning Koli as his behaviour showed all the signs of a psychopath, the officials said.
Koli and Pandher allegedly killed at least 15 women and children at the latter's home at Nithari in Noida.
