London - (AFP) - British police announced Tuesday that they had arrested a 20-year-old man after he threw an egg at King Charles III during his visit to Luton, north of London.

Bedfordshire police told AFP that the young man had been "arrested for questioning" for attempting to cause "bodily harm".

Charles III was visiting Luton to meet city officials and charities and visit a new Sikh temple.

In early November, a twenty-three-year-old man was arrested in York, in the north of England, after he threw eggs at the new king, while the latter was walking and shaking hands with those in the city center, accompanied by his wife, Camilla.

"This country was built with the blood of slaves," the young man chanted, before the police stopped him, at a time when calls are mounting to review the country's colonial past. The suspect was later released on bail.

Last week, the royal family witnessed a new controversy after statements described as racist were made by a close associate of the former Queen Elizabeth II to a black feminist during a reception at Buckingham Palace.
