DNA reports of Sajal Jain and Sugam Jaiswal have indicated their involvement in the gang rape of a woman in Ahmedabad on New Year's eve, sources said on Thursday.

"After detailed tests, we have found that Sajal and Sugam's DNA samples matched with the samples taken from the victim's body before she committed suicide [on January 7]," the sources said.

"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 sources said the test reports were given to the police on Wednesday.

Meanwhile, the police were awaiting court's nod to conduct similar tests with two other accused -- Chandan and Mandan Jaiswal, the sources said.

They were also waiting for the court's clearance to conduct lie-detector tests on the four alleged rapists, the sources said.

The 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 gang rape, but later the investigation indicated there was one more person with them, who is from Ajmer and is still at large.

The police said nine others, including two women, have been arrested for destroying evidence and sheltering the accused. All of them are in judicial custody.
