It looked like sheer fun grabbing "free money" from an armored truck, but 2 people were arrested

It was a free-for-all Friday morning after money flew out of the open door of an armored truck on its way to San Diego on Interstate 5. The paper cash scattered across a highway and people enthusiastically scooped it up — mostly $1 and $20 bills from a couple of bags that had broken open.

One enthusiastic couple took entertaining video of themselves shrieking, laughing and jumping with wads of cash in their hands, the woman shouting, "This is insane!" They looked like they were having the time of their lives. (Video below.)

While many people later returned the cash, two people, who got locked out of their cars, were arrested "at the scene," according to AP.

From AP:

Two people were arrested at the scene, and Martin warned that any others who are found to have taken the money could face criminal charges. He noted there was plenty of video taken by bystanders at the scene and that the CHP and FBI were investigating.

Anyone who took money was urged to bring it to the CHP office in Vista.

Authorities didn't immediately say how much money was lost. However, at least a dozen people had returned money they collected to the CHP by Friday afternoon, the San Diego Union-Tribune reported.

"People are bringing in a lot," Martin said. "People got a lot of money."
