The CBI on Friday arrested Krishna, the compounder of Noida dentist Rajesh Talwar accused of killing his teenaged daughter Aarushi and his domestic help Hemraj, for allegedly being involved in a criminal conspiracy for destruction of evidence.
CBI Joint Director Arun Kumar told reporters in New Delhi that Krishna was arrested on the basis of reports of polygraph test and narco-analysis test conducted on the compounder at Forensic Sciences Laboratory in Bangalore on Thursday.
“He (Krishna) was earlier subjected to polygraph twice at CFSL, Delhi. He was also subjected to psychological assessment test at AIIMS,” he said.
“Based on the scientific tests results, CBI arrested Krishna today. Further investigation continues,” the Joint Director said.
