The 21-year-old "Keeping Up with the Kardashians" star and model called police at 1:15 a.m. Thursday after she noticed expensive jewelry missing from her bedroom in her Hollywood Hills home, according to TMZ.
Sources later told the website Jenner hosted a party at her home Wednesday evening and left her friends alone in the house around midnight.
She discovered her jewelry box was open after returning just after 1 a.m.
The Los Angeles Police Department told E! News they received a call at 1:15 a.m. Thursday, but would not confirm if the call came from Jenner. The department said there were no signs of forced entry at the home.
"Officers did a search of the premises and no suspects were found," a spokesperson said. "[It's] an ongoing investigation."
The reported theft comes five months after Jenner's half-sister Kim Kardashian was robbed at gunpoint at her hotel in Paris.
The 36-year-old reality star, who lost millions of dollars worth of jewelry, tearfully recounted the incident in a preview for the March 19 episode of Keeping Up with the Kardashians.
