Austrian police have found a body they believe is a man suspected of shooting dead three policemen and a paramedic.
The charred body was discovered at the farmhouse where the man lived near Melk, Lower Austria, after special forces stormed the building.
Commandos searched the house, backed by about 100 police, as the suspect was reportedly heavily armed.
The drama began on Monday when officers tried to arrest the man on suspicion of poaching near the town of Annaberg.
The suspected gunman – named as Alois Huber, 55 – is thought to have been a notorious deer poacher who had evaded capture for years.
Police had tried to stop his car, but the man reportedly opened fire after heading into a ditch, injuring a police officer who later died in hospital.
A paramedic was shot dead as he tried to help the officer, and a second policeman was injured.
The gunman then fled on foot, killing a second police officer and taking a third hostage.
He stole their police car and drove, with his captive, to his farmhouse, about 90km (55 miles) west of the capital Vienna.
Officials later discovered the body of the third policeman at the farm. A large section of the area was cordoned off.
Three military armoured vehicles were involved in the operation.
Special forces eventually stormed the farmhouse after shots were fired at them.
Regional police spokesman Roland Scherscher said that during their search of the building, officers found a secret room.
“The room could only be entered through a door hidden in a wall,” Mr Scherscher told a news conference. “One had to push against the wall to enter the room. The police forced opened the door and wanted to enter the room. But it had been set ablaze.”
