Police are hunting for a teenage girl who is believed to have flown to London from New York after being in contact with an older man.
Victoria Grabowski, from Queens in New York, boarded a flight from John F Kennedy Airport on Saturday, local police said.
The 16-year-old is said to have arrived in the UK on Monday morning.
Police in the UK and the US have begun searching for the teenager.
According to US media reports her parents discovered texts showing she had been communicating with an older man in Britain.
She had also paid for her ticket in cash, though her parents did not know how she acquired the money.
"She left JFK on Saturday morning and reached the UK on Monday morning," a New York Police Department spokesman said.
"We're working in conjunction with UK police, but unless she contacts us, we're not going to know too much more."
US reports said Victoria is a Polish citizen and used her Polish passport to board the flight.
