A man has been arrested on suspicion of child abduction after police stopped a plane flying to Romania.
Nottinghamshire Police said they tracked down a man to Heathrow Airport after receiving a report that a four-year-old girl had been taken.
They received a call at 16:57 GMT on Thursday, and the flight to Bucharest was due to take off at 18:00.
The 32-year-old is known to the girl, who has been reunited with her mother, a spokesman said.
The plane was taxiing ready for take-off, but police got there just in time before it took off. It returned to the terminal and the man was arrested.
