California authorities say a registered sex offender who's banned from using the Internet was arrested while browsing Facebook _ next to a sheriff's detective in an Apple store.
Investigators say 35-year-old Robert Nicholas McGuire was spotted Wednesday in San Luis Obispo by the Sexual Assault Felony Enforcement Team and was followed to the retailer.
He was recognized from a previous child pornography case.
The San Luis Obispo County Tribune reports McGuire logged on to a display computer and a detective went to the system next to him and pulled up the Megan's Law sex offender website, which showed McGuire is prohibited from using the Internet.
McGuire was arrested outside the store and is being held without bail for investigation of violating probation.
A sheriff's spokesman didn't immediately return a message.
