German authorities say three teenagers aged 15 and 16 have been arrested over suspicion of plotting a deadly Islamist terrorist attack in the western German state of North Rhine-Westphalia, prosecutors said on Friday.

The state’s Central Office for the Prosecution of Terrorism (ZenTer NRW) sought an arrest warrant for the teenagers over the Easter holiday.

They were suspected of plotting a terrorist attack with the aims and ideology of (extremist militia organisation) Islamic State.

The detained suspects are a 15-year-old girl from Dusseldorf, a 16-year-old girl from the Märkischer Kreis district and a 15-year-old boy from the Soest district, located about 100 kilometres east of Dusseldorf.

A fourth suspect has reportedly been identified in the south-western German state of Baden-Württemberg, and the local court there has issued an arrest warrant.

According to the investigators, the teenagers are accused of having agreed to commit murder and manslaughter.
This is in conjunction with the preparation of a severe act of violence endangering the state.

The presumption of innocence applied in all stages of the proceedings.
Security sources told reporters that the young people had formed a chat group but had yet to draw up a concrete attack plan for a particular time and place.
