A teenage girl from Queens who went missing over the weekend — sparking an international search — was found in London Wednesday, police said.

Victoria Grabowski, 16 — who may have been lured to England by an older man she met online — was unharmed when authorities tracked her down, according to NYPD Chief of Detectives Dermot Shea.

“We’ll get her back here to her parents. She’s safe and sound,” Shea said during a press conference at 1 Police Plaza Wednesday afternoon. “She developed some sort of a relationship with a man… [and] got on a flight to London.”

Grabowski’s uncle, Arkadiusz, told The Post the man had been busted by cops.

“She is still in police custody in the UK. He was arrested,” he said — adding her family is breathing a sigh of relief. “Of course we are [relieved].”

It was not immediately clear what crime he’d been charged with.

The Maspeth teen vanished Saturday after her dad left for work, Arkadiusz said.

“When he came back a few hours later, between 12 p.m. and 1 p.m., she was gone,” he said. “When he came back and found the door to the house was open, right away he worried. It was unlocked. It [was] devastating.”

“After the fact, her parents tried to put the pieces together and found the text messages but before that, there was nothing unusual,” he said.

Later, the family discovered her plane ticket had been paid for in cash, he said — noting cops may have used her phone and computer to track her down.

He added, “She is a very quiet girl. She is very smart.”

NYPD intelligence officials teamed up with London Metro cops to find the teenager, officials said.

Grabowski’s mother, Renata, declined to comment.
