Police are urging parents in South Florida to check the online accounts of their children after three teens were accused of creating an Instagram account to solicit and post explicit photos of other minors.

Pembroke Pines police arrested two boys, ages 12 and 15, and a 13-year-old girl Thursday. They face charges of electronic transmission of child pornography.

The arrests followed a 10-week investigation.

Police say the social media account encouraged its 500 followers to post nude and sexually explicit photos of minors to "expose" them. The posts included their names and personal information.

Sgt. Drew Jacobs told the South Florida Sun Sentinel (http://bit.ly/1vq0FrT ) numerous youths were exploited. He said detectives are likely to release more information on Friday.

Pembroke Pines is a suburb of Fort Lauderdale.
