A local commander told Kurdish news outlet Rudaw that the arrested man was Muhammad Jamal Amin, a Virginia-born US citizen of a Palestinian father and an Iraqi mother.
The commander said that Kurdish forces fired on the man before he reached their base near Sinjar, and later detained him.
A number of cell phones, some money, and ID cards were seized from the militant.
According to the officer, who did not want to be named, the man mistook the Peshmerga territory for the Turkish border. The man had reportedly entered Syria from Turkey two months ago.
CBS News reported that the man identified himself as an Islamic State (IS, formerly ISIS/ISIL) defector who wanted to turn himself in.
Meanwhile, CNN reported that is was unclear why the man was in ISIS territory, or where exactly he was taken into custody.
