The bespectacled professor says he didn't realise the "rather intrusive young man" shouting that he shouldn't cross there was a policeman. "I thanked him for his advice and went on."
The officer asked for identification. The professor asked for his, after which Officer Leonpacher told him he was under arrest and, the professor claims, kicked his legs from under him, pinned him to the ground and confiscated his box of peppermints.
Professor Fernandez-Armesto then spent eight hours in the cells before the charges were dropped. He told the Times that his colleagues now regard him as "as a combination of Rambo, because it took five cops to pin me to the ground, and Perry Mason, because my eloquence before a judge obtained my immediate release".
