Top officers at Sussex Police have joined thousands of people worldwide to take part in the Ice Bucket Challenge.
Chief constable Giles York let himself in for a soaking when he accepted the challenge from chief constable of Surrey Police Lynne Owens.
He then set the chain rolling across the force nominating his chief officer team to carry out the challenge across the force.
Temporary deputy chief constable Olivia Pinkney completed the challenge at Gatwick, assistant chief constable Robin Smith at Brighton and assistant chief constable Steve Barry at Worthing.
Police cadet Sam Jarvis, from Hastings, who has been a cadet for two years, had the honour of tipping the bucket of ice over Mr York, who then repayed the favour for Sam.
Sam, 17, said: “It was such a privilege to tip the bucket over the chief constable and it’s completely different from anything else I’ve done in my time as a cadet.”
The officers are the latest to take part in the challenge which is sweeping across the world with people donating money and having a bucket of water and ice emptied over their heads.
The funds raised from the challenges from the four officers will go towards the Motor Neurone Disease Association in the UK and St Barnabas Hospice in Worthing in memory of friend and colleague Sergeant Neil Costello who the force said a sad farewell to on Tuesday (August 26).
Motor neurone disease, or amyotrophic lateral sclerosis (ALS) as it is known in the USA, causes a progressive weakness of many of the muscles in the body.
Motor nerves become damaged and eventually stop working. Therefore, the muscles that the damaged nerves supply gradually lose their strength.
For the vast majority of cases, it is not inherited and it does not run in families.
