A frightening team of zombies shuffled their way through the city before disrupting the calm of The Hepworth last weekend.
More than 60 monsters took part in the first ever scaretrek as they made their way to the gallery.
They were walking, and scaring, to raise awareness of the dangers of sudden cardiac arrest in sport and for the charity Heartbeat of Sport.
It was organised by Fear Masters Entertainment and raised £1,000 for the charity which will now be used to provide training and a defibrillator for Normanton Sports Acro.
Chris Walton, creative director at Fear Masters Entertainment, said: “I am delighted with the response from the public who wanted to find out more about the charity and the purpose of the walk.
“The amount of sponsorship money raised was most welcoming.”
Holly Rowney, of Sports Acro, said: “We are absolutely over the moon to be nominated to receive the defibrillator and training.
“This is something every sports club and school should have, it’s potentially a lifesaver.”
