Police say black IS flag was on Jakarta attacker

National police spokesman Anton Charliyan has told reporters a black IS flag was found with one of the Jakarta attackers and police believe they have established their identities.

He says two of the five men were previously convicted and imprisoned for terrorism offenses. He did not release any names.

Five men attacked a Starbucks cafe and a traffic police booth with hand-made bombs, guns and suicide vests Thursday, killing two people and injuring 20. The attackers were killed.

The scene of the deadly attack, in Jakarta's downtown business area, has been sealed off with metal fences. Traffic was flowing normally on Friday morning.

Police have told an Indonesian TV channel that they have arrested three men on suspicion of links to the attack in Jakarta.

Depok area police chief Col. Dwiyono told MetroTV that the men were arrested at dawn at their homes in Depok on the outskirts of Jakarta.

Dwiyono, who goes by one name, says the men are suspected militants and are being questioned over possible links to the attack Thursday that killed seven.

MetroTV broadcast footage of the handcuffed men being escorted by police.
