Officials said a crowd of about 50 people began hurling rocks at the BBC group Thursday as they drove in a caravan under police escort to the Chilean border in the southernmost province of Tierra del Fuego.
They were forced to leave the cars behind in an area between Tolhuin and Rio Grande. One minor injury was reported and images by local newspapers showed broken windows and other damage to the cars, which were taken into police custody.
The "Top Gear" crew was using three cars, one of them a Porsche bearing the license plate "H982 FKL," which some Argentines believed was a reference to the brief but bloody 1982 war in which the country tried and failed to capture the islands held by Britain.
The provincial city of Ushuaia, on the tip of Tierra del Fuego, is the closest spot in the Argentine territory to the South Atlantic archipelago and many military contingents were deployed from the town.
The British newspaper The Telegraph said the BBC denied the license plate was intentionally chosen. "Top Gear production purchased three cars for a forthcoming programme; to suggest that this car was either chosen for its number plate, or that an alternative number plate was substituted for the original is completely untrue," BBC executive producer Andy Wilman was quoted as saying.
In 2011, the BBC apologized to Mexico over remarks made on "Top Gear" that characterized Mexicans as lazy and oafish.
