23-year-old student Patrick Thelwell was found guilty of "threatening behaviour" after he threw "at least five eggs" at King Charles III and Queen Camilla during their visit to the city of York in northern England last November.
On that occasion, the young man had also opposed the historical mistakes of the crown, which according to him "were built on the blood of slavery".
Thelwell was tried at York Magistrates' Court for public order offenses and specifically for using threatening words and behaviour. He also egged a few royals as they greeted crowds in the English city.
Before today's hearing, the student posed for photographers, holding anti-monarchy banners with some activists. Another youth who targeted King Charles with an egg in Luton in December, 21-year-old Harry May, was fined £100 earlier this year for the act.
