Iran's semiofficial Fars news agency is reporting that a soldier has shot three policemen to death in the country's south.
The Saturday report said the incident took place at a police station near the port city of Bandar Lengeh, some 1,000 kilometers , or 620 miles, south of the capital Tehran.
It said the soldier was immediately arrested.
The report did not elaborate on a motive or the rank of the policemen saying only that the case is under investigation.
Such incidents are reported by Iranian media occasionally.
In 2016 a soldier killed himself after shooting to death three of his comrades in southern Iran.
Experts blame incidents on anger over the mandatory 2-year military service for men aged 19 and above.
