OREM — A 30-year-old man was arrested Saturday after police say he used a cell phone to take pictures underneath a girl's skirt.

Police were called after employees at the University Mall spotted the man taking the pictures of a juvenile girl, said Orem police officer Trent Colledge.

"He would bend down and take his phone and reach underneath their skirts," Colledge said.

The man was booked into the Orem City Jail for investigation of voyeurism. Police plan to serve a warrant for the man's phone today.
