Will Jenkinson, 22, spurred into action after his sister alerted him to a YouTube video on Wednesday evening (May 19).
YouTuber and Happy Hour podcast host Jack Dean better known as JaackMaate, revealed to his 1.4m subscribers that he had left a golden ticket in all 51 English cities, including Chichester, which could be worth up to £5,000.

"I saw it and realised it had 300 views. I got my shoes on and headed towards town. I was skipping through the video to see where it was.
"I've lived in Chichester all my life so I could see it was Priory Park straight away. It took me about five minutes to run there.
"There was one guy already there and I think he was quite irritated when I pulled it out of the nettles. I jumped in wearing shorts and had to rip through all the nettles with my bare hands."
Will said he is a 'big fan' of Jack's channel and has regular football debates with him on Twitter.
Every golden ticket left across the country will be worth at least £50 but five will be worth £500 and one person will be awarded £5,000.
"It hasn't really sunk in yet," Will said. "Bare minimum, I've won £50.
"Unfortunately. my sister is claiming half the money.
"I'd be the talk of the town [if I won £5,000]."
