Appearing as a prosecution witness, Dr Singh said the Central Bureau of Investigation (CBI) had asked for re-creation of the crime scene which was conducted on November 8, 2010, at Talwars’ L-32 Jalvayu Vihar residence with a team of CFSL and CBI officials.
“A CBI constable was told to lie down on a bedsheet and he was taken to the roof by two persons. On the roof, red colour was poured over the bedsheet and the constable again lied down and was dragged for about 25-30 feet,” Singh stated.
He stated that some dragging marks were created as a result and were similar to the marks which had appeared in pictures clicked by the local police after they were first called to the house.
Singh was the head of the team, including CBI’s present investigating officer AGL Kaul, which conducted the test.
