Police are looking for more victims after a 27-year-old man was accused of using Craigslist to run a fraudulent ticket ring.

The Toronto Strategic Partnership investigated allegations of a fraudulent operation involving the online sale of event tickets between March 2009 and December 2010, police said in a statement released Wednesday.

Police say the man advertised the tickets via the free on-line classified advertisement board using the aliases including: Sarah Lambert, Robert Cook, John Pearson, Megan Hinton, Jeff Costas, Amber Schultz, John Jonensen, Dan Evans, Ryan Lighty, and Mark Shaw.

When the time came to pay for the tickets, it is alleged that he obtained payment from victims but failed to deliver the tickets.

Roger Neiley, of Hamilton, has been charged with 20 counts of fraud under $5,000, 20 counts of laundering proceeds of a crime and 20 counts of false or misleading representations to the public.

He was scheduled to appear in court Tuesday.

Police believe that there may be more victims.

Anyone with information is asked to contact Det. Alan Spratt at 416-808-7300, Crime Stoppers anonymously at 416-222-TIPS (8477).
