(MCT) — LOS ANGELES — Los Angeles police arrested an unidentified juvenile in a series of “swatting” incidents that targeted celebrities, including actor Ashton Kutcher and singer Justin Bieber, department officials said Tuesday.

Authorities would say only that the suspect was arrested Dec. 10 at his parents’ Southern California home. They would not release additional details about his identity, exact age or background. The LAPD, which investigated the case with the Long Beach Police Department and FBI, cautioned that the investigation was ongoing.
