Kim Kardashian has claimed valuables were stolen from her luggage during a British Airways flight from Heathrow.
The reality TV star flew home to Los Angeles from London where she'd been promoting her latest fragrance and slimming products and spending time with boyfriend Kanye West.
The 31-year-old, who also attended the Cannes film festival before flying to Los Angeles from Nice via Heathrow Terminal 5, took to Twitter to accuse the airline of rifling through her possessions.
She tweeted to her 15 million followers: "Very disappointed in British Airways for opening my luggage and taking some special items of mine! Some things are sentimental and not replaceable."
She added: "What happened to the days when you could lock your bags! We need to get back to that. There's no sense of security and no trust!"
Among the items she claims were taken were a pair of sunglasses given to her by her father Robert just before he died, TMZ reported.
A British Airways spokeswoman said: "We are continuing to investigate this matter. Our customer travelled from Nice to Heathrow Terminal 5 to Los Angeles.
Terminal 5 has some of the most sophisticated automated baggage systems in the world, which are able to monitor bags every minute of their time in the terminal.
"At this stage, we have discovered no evidence to suggest that the bag in question was interfered with at Heathrow. Our investigation is also seeking to establish details of the bag's passage through Nice and Los Angeles airports."
A spokeswoman for Heathrow owner BAA said: "There are high levels of security at Heathrow. Passenger bags are electronically tracked and recorded throughout the system."
