The 24-year-old man was detained on Wednesday morning by the Finnish National Bureau of Investigation in cooperation with the local police department.

Jari Raty, detective chief inspector at the Central Criminal Police Department, told Yle that the man was allegedly involved in the Camp Speicher massacre conducted by ISIS in 2014. Some 1,000 to 1,700 unarmed cadets were killed in the incident.

The suspect arrived in Finland last autumn. The police did not reveal whether the man was an asylum-seeker or not. The pre-trail investigation was carried out in close cooperation with the Iraqi authorities, said Raty.

Last December, 23-year-old Iraqi twin brothers linked to the Camp Speicher massacre were caught by Finnish police in Forssa, southern Finland.

The case will start to process in the Pirkanmaa District Court of Finland on Aug. 25, according to Yle.
