The Danish man sentenced to life in jail for the murder of journalist Kim Wall aboard his homemade submarine was arrested on Tuesday after a failed prison escape bid led to a standoff with law enforcement, police said. "Peter Madsen tried to escape," a Copenhagen police official told AFP. On Twitter, police confirmed Madsen had been "arrested and removed from the scene" after being surrounded by police officers, with unconfirmed reports he had threatened them with a gun or an explosive device. po/pma
