A man accused of preying on young girls he met online for sex was arrested in an undercover sting in Anaheim, police said Thursday.
The case began when a 13-year old girl reported being sexually assaulted in a La Habra apartment in late 2014 by a then 26-year-old man, according to the Anaheim Police Department.
The Cypress teen told investigators she met the man online using the app called Friends Talk. It's described as a mobile messenger where you can make friends based on gender age and location.

"He was looking for 13, 14-year-old victims that he could lure to certain locations and then engage in sexual activity with them," said Sgt. Daron Wyantt of the APD.
The girl said she didn't know the man's true name or much about him, so the case went cold. Investigators went undercover posing as a 14-year old girl on the same app. They say 28-year-old Moonjun Kim reached out to them, so they agreed to meet at Chaparral Park in Anaheim on March 29. Kim allegedly showed up that day carrying a bag filled with rope, sex toys, lubricants and condoms, as well as recording equipment.
He was arrested at the park without incident.
"Kim also admitted he has engaged in similar encounters with females he knows to be underage," police said in a news release.
Kim is alleged to have used other social media apps like WeTalk, Line, Skype, Kakao Talk and Facebook to reach out to potential victims.
Police say parents should know how their teens are using their phones.
"Be very familiar with their online presence know what kind of apps they're using and know what kind of communications they're engaging in," Wyatt said.
Neighbors in Kim's La Habra neighborhood said he moved out a few weeks ago, about the time he was arrested.
"Clean cut, seemed like a real nice guy. Only talked to him one time but he seemed like a decent guy," said neighbor Gerard Martinez.
Kim is being held at Orange County Jail on $300,000 bail. He faces several charges including lewd acts with a child 14 or under, meeting a minor to commit lewd conduct, and distributing pornography to a minor with intent to engage in sexual conduct.
Police are asking for any potential victims to come forward by calling Crime Stoppers at 855-TIP-OCCS.
