A paramedic has denied sexually assaulting a drunken teenager twice while taking her in an ambulance to hospital.

Gerald Hendron prosecuting told jurors at Leeds Crown Court the allegations were made against Dale Kirby after they arrived at Huddersfield Royal Infirmary in the early hours of November 30, 2014.

He said the complainant, who was 18, had gone out in Huddersfield town centre the previous evening with friends celebrating the birthday of one of her group. She had been drinking wine and vodka before they went out and continued drinking wine but soon after midnight she was unwell.

Mr Hendron told the jury she remembered lapsing in and out of consciousness on a bench. They could not get a taxi to take her so walked her further to Cross Church Street where she was put in the recovery position and an ambulance was called.

Kirby was sent with a colleague from the Brighouse Ambulance Station and found the teenager and one of her friends both on the ground. He assessed the complainant as the most intoxicated and she was put on a stretcher into the ambulance.

Her friend, who was also drunk, was on a seat while a third friend sat with the driver in the front of the ambulance.

The complainant claimed at one stage Kirby looked around and then put his hand up the skirt of her strapless dress and into her knickers.

Mr Hendron told the jury the complainant would say Kirby then touched her for a second time. He said at the hospital the complainant was approached by a nurse who tried to get a sample from her and she resisted saying not to touch her adding: “He’s touched me, he’s touched me.”

When she was asked who she replied the paramedic in the ambulance. A policeman who was nearby heard the allegation.

Kirby, 34, has pleaded not guilty to two charges of sexual assault.

Mr Hendron said when Kirby was arrested and interviewed he said in the ambulance he had covered the complainant with a blanket and at one stage she had thrown it off and tried to pull down her knickers as though to go to the toilet.

He said he tried to pull her knickers back up and said in her movements her breasts and genitalia became exposed. When the ambulance went over a bump his fingers might accidentally have touched her and he said: “Sorry.”

The trial continues.
