It appears a severe incident took place in the correctional facility Iserlohn. Apparently a 17-year-old inmate attacked two officers of the facility with hot water.

The two officers allegedly suffered severe scalding. They were taken to a special hospital via helicopter. They are not in critical condition.

This is reported by „Bild“ newspaper. Accordingly, the attacker is a German who converted to Islam and who is under terror suspicion. According to the report, the young man tried to acquire weapons and explosives. He is accused of having prepared a grave subversive crime. According to „Bild“, he was arrested already in summer 2016. His trial began in December.

Police Started Investigations
The facility’s leader, Joachim Güttler, told the newspaper: „He refused to leave his room. Even his caretaker, with whom he got along very well, could not convince him. Suddenly, the attack happened.“

According to the report, the 17-year-old used a water cooker in his room to boil the water.

A speaker of the Ministry of Justice North Rhine Westphalia condemned the attack. He said to „Bild“ that attacks on officers were based on „an attitude of hostility towards the state“. Police took up investigations for grave battery.
