Three Hastings teenagers waved fake guns around town while claiming to be from ISIS.
The three 16-year-olds are now facing firearms charges.
The alarm was first raised at about 1.30pm today in Napier when members of the public were alerted by the group of young men with the phoney firearms and shouting that they were from ISIS, police say.
The group then made their way to Hastings where they again attracted attention from the public.
Police caught up with them at a Hastings house and when confronted, one of the boys threatened a police officer.
