A female assailant attacked police headquarters with a handgun and was shot dead after firing several rounds.

[12] National Police Chief General Listyo Sigit Prabowo said the attacker was an ISIL-affiliated lone wolf.

[13] The attacker had left a statement in which she apologized to her family, stated her willingness to die as martyr for Islam, and her deep hatred and resentment of things considered un-Islamic, namely Indonesia's institutions, ideology, and political system, as well as banks, and former Jakarta governor convicted of blaspheming Islam Basuki Tjahaja Purnama.

Its chairman, Benny Mamoto, questioned how guards at the entrance missed the concealed handgun.

He also urged the agencies to increase their intelligence capabilities to enable early detection.
