Parents of Aarushi Talwar, who was found murdered at her Noida residence about two years ago, have to undergo a series of narco-analysis tests which began on February 8 in Gujarat's Gandhinagar district.
While the tests are being conducted on her mother Nupur Talwar, her father Rajesh Talwar will undergo the tests from February 15 at the Forensic Sciences Laboratory in Gujarat.
"The tests on Nupur Talwar started on February 8 and will continue till February 12. The narco-analysis of Dr Rajesh Talwar will start from February 15 and will continue till February 20," official sources told PTI.
On January 5, the CBI had sought permission from a Ghaziabad court to carry out narco-analysis tests on the couple.
Aarushi (14) and her domestic help Hemraj were found murdered at their Noida house on May 16, 2008.
Though a narco-analysis test takes only three hours, in this case, the couple is subjected to the tests for nearly five days each.
