A man had over $18,000 worth of euros stolen from his car in Williston Park Friday, police said.

The victim, 38, exchanged $18,500 from a Bank of America on Hillside Avenue in New Hyde Park for approximately 16,959 euros before exiting in his Nissan Altima.

After parking at the Williston Townhouse Diner at 112 Hillside, a man went into the victim’s car from the front passenger door and removed the euros from his glove box, police said.

The thief, described as a white man in his 40s with a thin build, short unshaved hair and an unshaven beard, fled westbound on Hillside in what police said was a silver 2018 Kia Sportage.

Police are asking anyone with information on the incident to call 911 or 1-800-244-TIPS.
