Three men with suspected links to Thursday’s deadly attacks on Jakarta have been arrested, Indonesian authorities said Friday. The men were arrested at dawn at their homes and were being questioned over possible connections to the attacks, Police Chief Colonel Dwiyono told MetroTV. Just a day before, five assailants attacked a Starbucks cafe and a traffic police booth, leaving two people dead and injuring 20 others. All five attackers were killed by detonating suicide vests or by police. National police spokesman Maj. Gen. Anton Charliyan also said Friday that a black ISIS flag was found at the home of one of the attackers and two of the five attackers were previously convicted and jailed for terrorism offenses.
