DDA employee Lakshman Singh was presented before CBI special court here by the probe agency after Umesh refused to identify the two golf sticks mentioned in CBI's identification documents in a previous hearing on September 14.
The agency has claimed that golf clubs were used in the murders.
Singh said that he was sent to CBI office on August 2, 2010 by the Deputy Director (Personnel) where he met Umesh along with CBI officer I G Kaul.
"Umesh took out the golf sticks from the bag and showed it them to me," he said.
Meanwhile, Umesh's testimony ended today. The court declared him hostile in its last hearing on September 14 when he did not support the CBI's contention based on its evidence.
The next hearing of the case will be on September 19.
