The officer, named as Daniel S., was one of three police officers who responded to a silent alarm during the armed robbery of a Billa supermarket in Vienna.
When the news was announced, Austrian chancellor Christian Kern issued the following statement:
"Police officers put their lives in danger for the good of our society on a daily basis. They have earned our full respect and acknowledgement. Today, we have been tragically made to accept this risk that they take for us."
"My deepest sympathies go out to the family, friends, colleagues of the police officer who succumbed to the injuries suffered during the practice of his duty at Saturday's supermarket robbery."
According to local witnesses, the event took place near the Hanusch hospital. Two employees are believed to have been held at gunpoint in the supermarket after it was closed.
The dead robber has been identified as a Bosnian man (49), who is a suspect in at least two previous robberies. He was armed with a pistol with a silencer, and was described by police spokesman Paul Eidenberger as "a professional."
On Tuesday, police arrested Wolfgang A. (63), who is believed to be the accomplice of the Bosnian robber. He was described as a weapons collector, who had a variety of deadly weapons and munitions in his home. The alleged accomplice is suspected of driving the getaway vehicle.
