The Esztergom man who killed himself and a TEK agent with home-made explosives last Wednesday night had built a 38-metre long tunnel for himself leading from his house, Emergency Police reported.

The perpetrator appears to have stored on the property large quantities of chemical substance not available in Hungary without a permit, which become volatile at room temperature and can cause highly powerful explosions.

During the police operation the perpetrator opened the tank containing the chemical substance and the substanct hen mixed with the air.

The man wore a gas mask in the house, removing it only when leaving the house to negotiate with the police and was wearing it when the explosion occurred.

TEK agents had been attempting to negotiate with the man for 4.5 hours.

His intention was undoubtedly to kill the police officers, 444 writes.

A police officer injured in the blast was released from Budapest’s Honvédkórház hospital on Saturday but three of his colleagues are still being treated for injuries, one of them in the intensive care ward.

An agent of the Counter-Terrorism Centre (TEK) died during an operation at a family home in Esztergom on Wednesday night.

Police and firefighters went to the house on the outskirts of Esztergom in large numbers after receiving a threatening report.

The intruder in the house then detonated an unknown object, presumably a gas cylinder, and six or seven people were injured.

The injured are all TEK agents, of whom three suffered serious injuries.

The perpetrator died on the scene.
