British and American police are attempting to locate a 16-year-old girl who flew from New York to the UK on the weekend, reportedly after being in contact with an older man.
New York police said Victoria Grabowski, from Queens, boarded a flight from John F Kennedy Airport on Saturday and arrived in the UK on Monday morning.
US media reports say 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.
