Officers from Norfolk Constabulary are facing off with the county's firefighters in a football match this afternoon, to raise money for a little boy with cancer.
They're hoping to raise money for two year old Harry Deeba from Taverham who was diagnosed with Neuroblastoma last year.
Neuroblastoma is a rare form of children's cancer.
He's been undergoing treatment since his diagnosis, and his family are hoping that he'll be in remission when his scan results come back.
The form of cancer that Harry has is known to be aggressive, so his parents launched a crowdfunding appeal in an attempt to send him to the USA for a new form of treatment.
They're hoping that Harry will be able to have a vaccine in America which has been known to reduce the risk of the condition returning.
They're attempting to raise just under £240,000 for Harry to go to New York for the chance of him living cancer-free.
The day has finally arrived where we will find out who wins the bragging rights between @NorfolkPolice and @Norfolkfire. But most importantly raising funds for @NeuroblastomaVs. Raffle, tombola, stalls and a police car and fire engine too! Entry from 2pm, KO 3pm. #teamharry pic.twitter.com/dHLyMpmUvs— Mulbarton FC (@MulbartonFC) April 14, 2019
Mulbarton FC who are hosting this afternoon's match took to Twitter to share their excitement, saying that the two sides will be competing for bragging rights.
PC Andy Dye organised the match and said that the forces were more than happy to support a good cause: "I'm sure both sides will be trying their best to win but at the very forefront of our minds will be working together as one emergency services' family to raise as much money as we possibly can to help Harry and support his family in their fundraising appeal.
"His story has touched all our hearts".
They are currently less than one hundred thousand pounds away from their total.
The match is taking place at Mulbarton FC's home ground of The Common and kick off is at 3pm.
