Paris Hilton, 28, was reportedly left fuming after her bodyguards discovered a secret recording device planted in her private hotel suite in Dubai.
“It was some sort of transmitter by all accounts,” the Daily Express quoted a source working with the hotel heiress as saying.
“We’re not sure what the device picked up or whom it was transmitting to. But it did leave Paris very jittery.
“Everyone she has come into contact with during her stay in Dubai has been fantastic and gracious. We’ve been told there are some quarters where there is anti-American feeling.
“Paris’s security has been increased and hotel staff are investigating how the device came to be in her room,” the source added.
The 28-year-old’s security has now been beefed up during the filming of her reality TV show My New Best Friend Forever.
