Peter Madsen, the man known for killing and dismembering a Swedish journalist while aboard his homemade submarine, briefly escaped a prison where he is serving a life sentence.

Madsen, 49, escaped from Herstedvester Prison, located near Copenhagen, Denmark, on Tuesday morning. He was able to escape by using a fake explosive belt and a fake gun, according to the New York Times. His freedom was short-lived, and Madsen found himself surrounded by police officers a half-mile away from the prison just five minutes after the getaway.
