"Both the DNA strands have matched and it does indicate that the duo was involved in the sexual assault on the victim," they said.
The state Forensic Science Laboratory (FSL) sources said the DNA test report (of Sajal and Sugam) was given to the police on Wednesday after tests on the samples began two weeks ago.
Meanwhile, police are still awaiting court's nod to conduct similar tests with two other accused Chandan and Mandan Jaiswal's DNA samples and are yet to collect their blood samples for this.
Officials are also yet to get a court clearance to conduct lie-detector test on the four alleged rapists, the sources said.
Banking completely on gathering scientific evidence in this case, police had got several stains from the car used by Sajal during his trip to Ahmedabad from Delhi on the night of the incident.
Officials initially had said that five persons were part of the alleged gang rape but later the investigation indicated there was one more person with them, who is from Ajmer and is still at large.
In all, two persons are yet to be arrested in the alleged gang rape case, police said adding, nine others, including two women, have been arrested for destruction of evidence and sheltering the accused. All of them are in judicial custody.
