JENSEN BEACH, FL (WFLX) - Forty Treasure Coast students have prom night memories they'd rather forget.
The Jensen Beach High School students say they showed up to prom Saturday night in a party bus – and each had to undergo a Breathalyzer test.
They said they were told they had to stay outside until every student was tested.
They say all of the tests came back clean -- but by the time it was all done, the prom was over.
A spokeswoman for the Martin County School District says there were items on the bus that were suspicious so they tested all the students.
Some girls on the bus said school employees found a bottle of champagne -- and the students say it must have been left on the bus from a previous customer.
They say all the tests came back negative for alcohol but the district spokeswoman says the students didn't arrive to prom until 10:30 p.m. and by the time the testing was finished it was too late to go inside.
Some parents are outraged.
"This was not handled correctly. Definitely not handled correctly. And I am upset about it," said parent Elliot Ziegler. He added, "This is something that is a lifetime. They are never going to have it. They are never going to have it. You can't recreate it."
The school district says this is an unfortunate situation -- but it has to ensure the safety of all students.
The district requires everyone going to prom to sign a zero tolerance policy that says they can be searched and tested.
