(CBS) Robbers wearing masks like those in the popular horror movie "Scream" stole more than 300,000 dollars from the driver of an armored vehicle who was delivering money to a Philadelphia bank on Halloween, reports CBS Philly.
At first, the victim thought the heist was a prank, reports the station.
The incident happened shortly after 9:30 Thursday morning as two masked men carrying TEC-9 style weapons approached the armored vehicle outside a Wells Fargo bank in Philadelphia's Holmesburg section, according to CBS Philly.
The station obtained exclusive surveillance video of the robbers' van speeding away.
They reportedly made off with hundreds of thousands of dollars in cash in a green minivan, which authorities later determined had been stolen after it was discovered abandoned.
The driver of the vehicle wasn't harmed during the theft.
"It's obviously a well planned robbery," FBI Special Agent in Charge Edward J. Hanko told the station.
The heist was "over in seconds," police said.
