The National Police has investigated a family of three who were captured by Turkish police for allegedly intending to cross the Turkish border to join the Islamic State (IS) group in Syria.
"They have confessed that they were crossing the border to join IS," National Police spokesman Insp. Gen. Anton Charliyan told reporters at the police's headquarters on Monday.
Anton did not give the names of the family members, a man with his wife and mother.
Captured upon arrival in Istanbul after a flight from Tehran, the family was deported to Indonesia on June 18 and is now under control and treatment at the Social Affairs Ministry. They will be returned to their hometown after treatment.
"We've released them because there is no indication of any violation of criminal law," Anton said, adding that the police would continue to monitor them after release.
According to Anton, the family had no external funding to finance their trip to Syria.
"They used their own money because they said the intention came from themselves. There was no involvement from other parties," he said.
The capture of the three adds to the list of Indonesians who have travelled to the war-torn region to fight for IS. Earlier this year, Turkish police detained and deported 16 Indonesians suspecting of trying to cross the Turkish border into Syria.
