Multiple officers were injured in an explosion outside the police headquarters in the Indonesian city of Medan. The blast is suspected to be a suicide bombing.
A university student blew himself up in a suicide bombing outside police headquarters in the Indonesian city of Medan on Wednesday, police alleged.
The attack came just one month after an Islamist militant attacked a former security minister.
Local police spokesman Dedi Prasetyo said security procedures had been in place, but the attacker ignored instructions when officers tried to check his backpack.
The national Densus 88 anti-terrorism unit said it was investigating whether the 24-year-old bomber had any links to radical
groups such the Islamic State-inspired Jamaah Ansharut Daulah.

Increased threat: Indonesia is the world's largest Muslim-majority country. It has suffered a string of terrorist attacks since the turn of the century. More recent strikes have been blamed on Islamic State-inspired militants. Indonesia's counterterrorism force has so far arrested 40 suspects since receiving a tip last month about potential attacks on police facilities. In August, authorities shot and arrested a militant who attacked officers at a station in Surabaya. In June another was seriously wounded when he tried to blow himself up outside a police building on Java island.
