An 800-word, untitled short story, unofficially known as the Harry Potter prequel, was written by J. K. Rowling in 2008 as part of a charity auction event, for which it fetched £25,000.
Two Muggle policemen chase a speeding motorbike into a dead-end alley, cornering its riders: Sirius Black and James Potter.
Thirteen authors, including Rowling, were invited to write stories on an A5 card for auction with proceeds going to English PEN and Dyslexia Action.
Rowling tweeted about the incident, asking fans not to buy the work if offered it, and West Midlands Police appealed for information.
