A saliva stain on the T-shirt of the victim of a fight allegedly involving N-Dubz rapper Dappy has a "billion-to-one" DNA link to the singer, a court has heard.
A trial at Guildford Crown Court was told Dappy sparked a "mob attack" when he spat at two girls who refused to get into a car with him and two friends at a petrol station in the early hours of the morning.
The spit missed the girls but he then spat at another person, David Jenkins, who had stood up to defend them before becoming subject to the attack himself, the court heard.
Dappy, charged under his real name Costadinos Contostavlos, swung a punch at him before Mr Jenkins put the rapper in a headlock, the trial was told.
Forensic scientist Carolyn Smith told the court that saliva linked to Dappy was detected on Mr Jenkins' T-shirt. When asked if the saliva could have been wiped on to the T-shirt sleeve as a result of the headlock, she replied: "It could have been that way, there are numerous options."
Brian Stork, prosecuting, told the jury Dappy, 25, pulled up in a car at the Shell garage in Woodbridge Road, Guildford, Surrey on February 28 last year. He and a friend, Kalonji Stewart, got out of the car along with a third man. While Stewart went inside the shop Dappy began talking to the girls, Grace Cochran and Serena Burton, who were in a group sitting on the kerb outside.
Mr Stork alleged that Dappy asked the two girls to come with them in their car, and when they refused called them sluts, said one was ugly and spat at them, but missed. Mr Stork said after Mr Jenkins was spat at, Dappy swung a punch at him and violence "kicked off".
Dappy was joined by two other men, Kieran Vassell and Alfred Miller, who had arrived in a second car with other unidentified men.
Dappy denies two counts of common assault on the two women, one of assault by beating, of Mr Jenkins, and one of affray. He's charged alongside Vassell, 25, of Hammersmith, west London, and Stewart, 32, of Harborne, Birmingham, who are each charged with affray.
Miller, 28, of Brentford, west London, has pleaded guilty to affray and his case was adjourned for sentence at the end of the trial.
