SALT LAKE CITY (AP) — A Spanish tourist protesting that she was ordered to pay a traffic ticket immediately sparked an investigation by Utah authorities that found local police targeted foreigners visiting Zion National Park to settle their driving infractions in cash.

The practice is illegal, Utah state auditors said in a report issued Monday. They said 138 traffic citations Springdale police issued from a larger book of tickets last year are missing together with an unknown amount of cash.
