The 44-year-old was drawn in by a Twitter stunt in which an unknown fraudster posted as Coronation Street actor Derek Griffiths.
Paddy shelled out £600 on online auction site eBay for a charity dinner with the soap star.
However, it turned out to be nothing more than a trick.
Despite details of the dinner being posted on a verified Twitter account fro Derek, in reality the page did not belong to him.
Revealing details about the incident on Twitter, Paddy wrote: "Morning, not a good start to 2018.
"I paid over £600 to a supposed Autism charity for the below. Turns out this sack of s*** has been scamming money off people under the guise of charity for a long time.
"Next stop for me is @gmpolice to report this scumbag."
The funny-man later continued: "Thanks for the response folks.
"Hearing about people stealing money from charity has always made my blood boil.
"Look at the good people he’s scammed out of money destined for good causes."
The incident is under investigation by the police.
Derek, 71, found fame in the 1960s after landing countless roles on children's TV shows.
