A murderer who killed a journalist on a homemade submarine has attempted to escape prison.
Armed police are on the scene and a road has been blocked off after Peter Madsen made a break for freedom from Herstedvester Prison.
Unconfirmed reports from Expressen and Aftonbladet claim that the inventor fled by warning prison officers that he had a bomb and by taking a hostage.
After a lengthy stand-off about 500m from the prison Madsen was detained in Albertslund, Denmark.
Madsen was seen sitting against the wall with some kind of belt around his stomach guarded by snipers after making it roughly 500m from the prison.
He remained in that position, with guns trained at him, at 1.00pm local time.
Although it is not clear how he would have gathered the necessary ingredients to make a bomb, it is likely Madsen has the technical know-how to make an explosive.
Journalist Kristian Linnemann, who has spent hours interviewing the murderer, told BT: “He knows what to use to build a bomb.
“Peter Madsen knows everything about chemistry and technology, so if he has the right ingredients, he will easily be able to build a bomb, but I doubt he has.”
Forensic psychologist Henrik Day Poulsen added: “We are dealing with a man who has committed one of the most bestial murders in Danish history, and precisely because he can use his talent for something dangerous, it is very worrying that people do not take better care of him.”
Witnesses on the ground reported that bomb experts were slowly making their way towards them shortly before 1pm local time.
Police are expected to make a statement later today.
According Ekstrabladet the killer had been isolated in prison after an his escape plot came to life.
A witness told the publication that he had been chased as he made his sprint for freedom.
“Suddenly I saw several guards come running across Roskildevägen,” they said.
Police confirmed that a man had tried to escape the prison, but did not provide any specific details.
In April Madsen was sentenced to life without parole after being found guilty of the premeditated murder and sexual assault of journalist Kim Wall.
The 30-year-old journalist had secured an interview with the eccentric inventor Peter Madsen on board his home-made submarine UC3 Nautilus in August 2017.
She boarded the sub off a harbour in Copenhagen on August 10 but failed to return.
The submarine sank and Madsen was later rescued, but there was no sign of Kim.
The next day Madsen was arrested and found to have flecks of Kim’s blood on his nostrils, scratches on his forearms and traces of semen in his underpants.
Two weeks later Kim’s headless torso was found on a nearby beach.
Arms, legs and a head determined to be that of the victim were also later retrieved by the authorities.
Police claim the submarine sank due to a deliberate act.
At his original trial he claimed Kim’s death was an accident but admitted to chopping up her body and throwing her over board.
He claimed Ms Wall died from breathing exhaust gases that had leaked into the submarine due to a technical error while he was on the deck of the vessel preparing to submerge.
Earlier this year Madsen admitted for the first time to murdering her.
