WASHINGTON —Two girls, who are 10 and 11, have been charged as juveniles in connection with threats made against another girl, Prince William County police said.

Police in the Northern Virginia county said the two girls communicated by text to conspire to kill the victim, who is 11-years-old.

The 10-year-old and 11-year-old used cryptic language and encouraged each other to delete the text messages after the threats were read.

On April 25, police responded to the girls’ school after a concerned parent alerted school staff.

In a statement, police said after extensive consultation with the Commonwealth Attorney, the girls were charged with conspiracy to commit a felony.

The threats were not carried out and no one was harmed, police said.

Details of the alleged threats were not disclosed nor was the name of the school the girls attended.
