Officials in Sanpete County say a teenage girl was sexually assaulted after taking part in a popular text message game.

Investigators say Issac Alonso initially messaged the girl's father while doing the so-called 'Number Neighbor Challenge,' where people send random text messages to their exact phone number, but with one digit changed.

The victim claims Alonso later assaulted her while they were on a date.  He's now jailed and charged with rape.
