PLAINFIELD, Ind. (December 18, 2015) – The FBI has announced they are taking over the investigation involving threats made to Plainfield High School and students on Facebook.

The announcement comes as Facebook threats continue to appear from an anonymous source. The details in the posts are graphic and disturbing. FOX59 has decided not to share those details.

All after-school activities are canceled at Plainfield High School. Friday night’s girls and boys basketball games are rescheduled.

The Indiana State Police Internet Crimes Against Children Task Force is assisting the FBI and the Plainfield Police Department with the investigation.

Gary Coons with the Indianapolis Department of Homeland Security said his team has not been called in for assistance. He said they will step in as soon as a threat appears that involved Indianapolis.

Coons said his team has been following the Facebook posts and are well aware of the situation. He said the posts are seeming to escalate, which is concerning.

“Sometimes this happens where it starts off small and then it just keeps growing because certain things aren’t happening that the one individual,” Coons said.

Coons is urging students and parents to come forward anytime they feel threatened. He’s also encouraging people in Indianapolis to anonymously call crime stoppers at 262-TIPS to provide information regarding threats to the community. He said the Department of Homeland Security closely monitors all tips they receive.

“If they’re being threatened or if there’s a situation that they know of, to say something or to tell somebody,” Coons said. He added, “if we’re alerted early enough then hopefully we can mitigate the situation before anything occurs.”

The Plainfield Police Department provided this statement Friday afternoon:

The Plainfield Police Department has been working with the Internet Crimes Against Children Task Force (ICAC) since the beginning of this investigation. The ICAC Task Force consists of Local, State, and Federal officials who work together to investigate Internet Crimes Against Children. The Plainfield Police Department will continue to work with the ICAC throughout the duration of this investigation.
