THE HAGUE, Netherlands—Smartly dressed robbers wielding what appeared to be weapons and a sledgehammer snatched jewelry in a brazen heist Tuesday at an international art fair in the southern Dutch city of Maastricht. Police quickly made two arrests and said they were hunting more suspects.
Video purporting to be of the robbery and posted on social media and on the website of Dutch broadcaster NOS showed one man, dressed in slacks, sneakers, a jacket and cap pounding at something out of picture with a sledgehammer as an alarm rang. Three other men, also neatly dressed, stood guard around him. At least two appeared to be brandishing guns.
