Colorado officials are investigating complaints about a second round of sexting involving schools.

Chaffee County authorities said Thursday they're looking into reports of sexting at a Buena Vista middle school and high school.

The announcement came one day after prosecutors in neighboring Fremont County said they wouldn't file charges against more than 100 students involved in sexting at a high school in Canon City.
 

Prosecutors said they found no evidence of coercion or bullying in Canon City, and no images were posted on the Internet.

It wasn't clear whether there was any connection between the investigations. Chaffee County Sheriff John Spezze declined to comment Friday. Buena Vista School District officials didn't immediately return a phone call.

Buena Vista is about a 90-minute drive from Canon City.
