A spillage from an armored van sparked a scramble and police arrests on a US motorway on Friday.
Videos on social media show money raining down as people scramble to pick up dollars strewn across the road.
It happened on the Interstate 5 in California’s San Diego county.
Police said the ensuing excitement saw drivers abandon their vehicles and block traffic. Arrests were made, with others who pocketed cash urged to hand it back.
One of the armored vehicle’s doors popped open on the road, causing bags of cash to fall out and break apart at about 09:15am local time.
“For whatever reason, money was falling out of an armored car,” California Highway Patrol (CHP) Officer Jim Bettencourt said.
“It was free-floating bills all over.”
Two arrests were made at the scene, local media reported.
Highway police officials said the FBI were involved and urged people who grabbed cash to come forward.
Officer Bettencourt said anyone who stopped to pick up money could “possibly be facing charges”.
“If a bunch of TVs fell from a truck across the freeway, you can’t just take the TVs,” he told San Diego Union-Tribune newspaper.
Curtis Martin, a sergeant with the CHP, said on Friday afternoon that about a dozen people had returned money they had grabbed to police.
“People are bringing in a lot,” he said, without giving a figure. “People got a lot of money.”
