RIVERVIEW, Fla. – Police in Hillsborough County, Florida are working to track down a Richard C. Spoto High School student who allegedly robbed a classmate carrying a cashbox with $3,000 raised for the prom.

Police said a student was taking a cashbox – with about $3,000 in prom ticket sales – from the lunch room to the school office around noon Wednesday when two students snatched it from him and ran out of the school, through the parking lot, down a bus ramp and across a football field, The Tampa Tribune reports.

“It was just like a wave of disappointment. I wouldn’t really expect it at Spoto,” senior class president Emma Shah told WFLA. “I just can’t imagine … someone running up to you, just grabbing it and leaving.”

Spoto principal David News told the news site there was security in place as students sold the tickets in the lunchroom, but they apparently did not escort the student to the office.

“The assistant principal and our deputy (are) right outside to man the selling process so it’s the way it’s been done here for 10 years,” News said.

Hillsborough sheriff’s deputies said they arrested one of the teens who returned to school after the heist, but neither he nor his parents are cooperating with investigators. They are still working to track down the second suspect, which witnesses described as black or Hispanic wearing a white t-shirt and short dark hair with an edge cut in the back, officials told the Tribune.

They’re encouraging anyone with information to call the sheriff’s office or to make contact online through the website crimestopperstb.com.

Many folks believe the parents of the teen who was arrested are likely part of the problem.

“’He and his parents are not speaking to investigators.’ What fantastic role models,” Harold Scott posted to Facebook. “Shows that the apple never does fall far from the tree. I bet the police know ma and pa better than they know junior.”

“They refuse to talk to investigators? Parents might be in on it,” Ashley Nicole Duke wrote. “Next time they need cops, fire, or EMT, they should refuse to go to their house.”

Other believe school officials should have took better precautions in transporting the money to the office.

“Why was the student walking with the cash box alone?” Jo Marie questioned. “Shouldn’t an adult have been in charge of the money?”

“Sounds like an inside job,” Casey McMahon added.
