Greek authorities on Friday said they had arrested a Syrian man suspected to be member of the Islamic State terrorist organisation.
Police said that they found incriminating data, videos and photographs, including scenes of executions, on his mobile phone.
He has reportedly confessed to being a member of Islamic State.
The 32-year-old, who arrived illegally with his wife and two children on the island Leros in June 2016 after traveling from Turkey, was arrested on Thursday.
The family moved through several refugee camps after their arrival, planning to continue further north to Europe.
Police became aware of the suspect after his wife filed a report alleging violence against their children.
The man is due to appear in front of prosecutors on Saturday.
Report says authorities are still checking the suspect’s background prior to his arrival in Europe.
