A 15-year-old Singaporean girl was almost refused the right to board a plane at Guangzhou Baiyun International Airport on Monday due to her phone's rather bizarre ring tone.

Security guards in the airport got a start when they heard a voice shouting, "I am a terrorist."

The "voice" was soon found to be coming from the young Singaporean woman's mobile phone.

The girl was immediately required to delete the strange ring tone. She was allowed to board after getting a severe telling off from the airport security officials.
