Rajkumar, the domestic help of the Durranis, underwent another Narco-analysis test. The person has already been subjected to various tests like narco-analysis, psycho-analysis, lie detector and brain-mapping after which he was placed under arrest on 27 June 2008.

On being asked as to why another test had to be conducted on Rajkumar, the CBI said that the first test had been inconclusive. It is also learnt that the CBI has seized a blood stained T-shirt from Rajkumar’s room. However it appears that no worthwhile information is being obtained by CBI on the subject.

Krishna, the Compounder of Dr Talwar, stated that Rajkumar was present in Arushi’s house on the night she was murdered. However he gave contradictory statements during his Narco-tests. The entire investigation revolves around these two key suspects. The T-shirt seized from Rajkumar has been sent to Hyderabad for DNA sampling and the results are awaited.
