Los Angeles police are investigating death threats made against 5-year-old Good Luck Charlie
star Mia Talerico, authorities confirm to PEOPLE.
Talerico, who plays Charlie on the Disney Channel show, initially received frightening messages on her Instagram page in January, according to TMZ

Law-enforcement officials did not elaborate on the contents of the death threats.
