A painting by Vincent van Gogh was stolen early Monday morning from a Dutch museum. The painting, an 1884 work titled The Parsonage Garden at Nuenen in Spring 1884, had been on loan to the Singer Laren museum near Amsterdam. It is part of the permanent collection of the Groninger Museum, in the northern part of the Netherlands.

According to the Dutch news website NL Times, police said the break-in took place at about 3:15 a.m. local time. The thieves smashed through the glass door at the museum’s entrance and only took the van Gogh. Police have been investigating the theft. The museum had been closed since a month due the outbreak of coronavirus pandemic.

According to CNN, museum director Jan Rudolph de Lorm said at a news conference on Monday afternoon, “I am shocked and unbelievably pissed off,” continuing: “It is very bad for the Groninger Museum. It’s also very bad for Singer.”
