Swedish police on Wednesday tightened border checks after a valuable artwork by Norwegian painter Edvard Munch was stolen from a manor in southern Sweden, police said.
Thieves broke into the summer home of a Norwegian ship owner near Horby, 360 miles south of Stockholm, late Tuesday and stole the painting worth an estimated $138,000, police spokesman Per Jansson said.
"The thieves just broke open one of the doors, removed the painting and left," he said.
Jansson said he did not know the name of the painting. Police stepped up border checks and launched an investigation, he said.
Works by the Norwegian painter, who died in 1944, are a popular target for thieves.
A version of his most famous painting, "The Scream," as well as "Madonna," were snatched by masked gunmen from the Munch Museum in Oslo in August 2004. Three Norwegian men were convicted of the theft, but despite an international police hunt the paintings have not been recovered.
