Los Angeles County sheriff's officials are looking for the person who falsely reported an emergency at the home of the Kardashians.
Sheriff's spokesman Steve Whitmore says it's too soon to tell whether the reality TV stars are the latest victims of so-called "swatting," a hoax intended to get officers, including specialized so-called SWAT teams, sent to a home.
Deputies who responded to the call Friday found no crime had been committed.
Kim Kardashian on Twitter called the hoax "dangerous" and "not a joke."
Police last week responded to a false report of an armed robbery at Tom Cruise's Beverly Hills home. In December, a boy was arrested after police said he made calls that reported violence at the homes of Justin Bieber and Ashton Kutcher.
