The Danish man sentenced to life in jail for the murder of journalist Kim Wall aboard his homemade submarine was surrounded by police on Tuesday after a failed prison escape bid, police said. "Peter Madsen has tried to escape," a Copenhagen police official told AFP, adding that "a police action is still ongoing." Pictures from the scene show Madsen sitting on the grass by a leafy wall next to a road with two police officers lying prone on the ground pointing their weapons at him, amid unconfirmed reports he was threatening police with a gun or an explosive device. po/txw
