ANOKA (AP) - Anoka County authorities say two 13-year-old Andover girls who went missing have been found unharmed in the Burnsville home of a 23-year-old man who they met online.

The sheriff's office says the man was arrested Tuesday on pending charges of soliciting sex and third-degree sexual assault. Authorities say he has worked at area schools as a girls' softball and volleyball coach.

They say the girls were last seen Monday night and an initial investigation generated "grave concerns." Investigators went through electronic devices that the girls used and found sexual communications with multiple men on social media.

Authorities say they used the devices to locate the girls at the man's house. They say the man picked them up near their homes Monday and they seemed to have gone with him willingly.
