At least six people have been injured after the attacker blew himself up outside the police headquarters in Indonesia's Medan city on Wednesday.
According to reports, the bomber, identified as a 24-year-old university student, walked into the compound around 8:40 am (local time).
The motive behind the attack was not immediately clear, but initial investigations have revealed that the student was a "lone wolf" but authorities are still trying to establish whether he had links to any militant groups.
It comes just a month after an IS militant attacked a former security minister.
Police said the six people – five police officers and one civilian – injured in the attack have been shifted to nearby hospitals.
"All pieces found at the scene will be tested by a forensic lab to determine the type of bomb," a top police officer told the media.
