POLICE today issued a fresh plea for information following the death of Jolene Potter-Connolly.
The 23-year-old suffered horrific injuries as she was dragged to her death by a car in the early hours of Thursday.
Jolene, of Almondbury, died after a fight broke out in the car park outside the Folly Hall leisure complex in St Thomas's Road, Huddersfield, at 2.30am. Police believe some witnesses have still not come forward.
Det Insp Sam Cooke, of Huddersfield CID, said: "It is imperative we trace everyone who was in that car park and saw what happened on Thursday morning.
"We now know from people that others were there, yet we have so far been unable to contact them.
"We need them to come forward and talk to us."
He added: "The car park was busy with people leaving the nightclubs at that time of night.
"People were in cars and others were on foot."
He stressed that the trouble happened solely in the car park - not the nightclubs.
"From all the statements we are getting, this all started in the car park," he said.
"We have several good leads to follow up."
The Ethos and Visage nightclubs stopped the music last night while an appeal was made for witnesses to come forward.
A similar plea will be made again tonight.
The car park is shared by Ethos and Visage along with the Grosvenor Casino and Jumpin Jaks.
Police have seized the car involved in the tragedy and detailed forensic tests have been carried out on it.
Jolene gained an honours degree in business studies from Huddersfield University this summer and had been due to marry an American man soon.
Three Huddersfield men - two aged 25 and a 17-year-old - were arrested on suspicion of murder and released on police bail pending further inquiries.
Anyone who saw what happened or has any information should contact Huddersfield CID on 01484 436582 or the main police helpdesk on 01484 436659.
