A photo of a large $120 order at a Carl's Jr. Restaurant led to the arrest of four car robbery suspects in Sacramento, Calif. Sunday.

Three adults and one teen posted a photo to Instagram bragging about their $120 splurge at a Carl's Jr. restaurant purchased with a credit card stolen from one of four vehicles they robbed Sunday, Nov. 10, according to The Huffington Post.

Investigators who tracked the card's use and contacted the Carl's Jr. restaurant where the purchase was made, discovered that employees had thought the transaction was suspicious and wrote down the license plate number of the car the suspects drove.

Sisters and co-workers Danielle and Katelyn Hubik were further suspicious when the suspects requested that they take photos of them with their large meal, according to CBS Sacramento. The suspicious sisters told police about the request, leading officials to check Instagram.

Three of the suspects have been identified as Tavion Spignor, 19, Leroy Jackson, 27 and Malek Morgan, 20.

"I was the one who wrote down the license plate, because I thought it was weird," Katelyn told The Sacramento Bee. "We never get orders that big, never."

The order reportedly included the following: five $6 burgers, five orange crème shakes, three barbeque chicken quesadillas, one bacon Swiss chicken sandwich, two double western sandwiches, two orders or fried zucchini, six orders of cross-cut fries, two teriyaki burgers with added bacon, two barbeque chicken sandwiches with added bacon and five southwest chicken tacos.

The suspects were arrested after the car in the photo was spotted at a Walgreens in Rocklin, Calif. They were charged with suspicion of auto burglary, conspiracy, possession of stolen property and unauthorized use of personal ID.
