"The armored auto crew said the side door came open while they were driving and money spilled out onto 285", Dunwoody Police said in a statement.
A side door on a Gardaworld truck unexpectedly opened as the vehicle was driving westbound on I-285 near Ashford Dunwoody Road outside Atlanta.
About 8 p.m., police responded to 911 calls that more than 15 vehicles had stopped on the busy interstate to pick up money that had fallen off an armored vehicle.
According to WSB, an armored car's side door came open and a "substantial" amount of cash flew out on the interstate. It isn't clear how exactly how much money was lost during the incident, but the truck crews estimated that it was around $100,000.
But officers and the Garda World truck crew only managed to gather a few hundred dollars from what was left over.More news: Somali-Canadian journalist Hodan Naleyeh dies in Somalia extremist attack
'While we certainly understand the temptation, it's still theft and the money should be returned, ' Parsons said via a statement from Dunwoody Police on Wednesday.
It's a crime for those who took the cash to keep it.
Meanwhile, videos circulating on social media show the frenzy caused by the spilled cash.
Police urge motorists to return the money plucked from the roadside.
A Reddit user who shared the video only 20 minutes after the incident said it was $1 bills. "The money needs to be returned to the owner".More news: Tropical Storm Barry Creeps Closer As Gulf Coast Prepares To Be Drenched
"If the money is turned in, we will not criminally charge those who do the right thing", Sergeant Parsons said.
As of Wednesday night, Police said five people turned in money.
Speaking to CNN, he said: "It took me a minute to realise it wasn't leaves".
