BRAINTREE, Mass. (WHDH) -- Hundreds of student across the Bay State were locked out of their school after it abruptly shutdown. Without warning, the American Career Institute closed its campuses.

Thursday, dozens of student showed up to find that there were no more classes at the American Career Institute campus in Braintree. That school was just one of five Bay State locations that shutdown Wednesday afternoon, without notice.

“It’s like a knife through your heart,” said Mim Pierre, a student. “It’s like yesterday you wake up, you have class, you have homework, you have finals. Then the next day you wake up and there’s no more school.”

Some students found out Thursday morning as they watched people remove furniture from the building.

“How can you just tell someone in the middle of the day that there’s no more school, that you have no more job,” said Sarah Coleman, who had one class left.

The for-profit school offered programs in medical, dental and technical fields.

A note posted on the door, which was the same one handed to students, cited financial reasons. It read in part, “The owners had to make the difficult decision to close the school due to its recent and unanticipated inability to access additional credit from the schools lenders.”

Students are now worried about their own finances.

“I gotta get all my loans back. The whole nine, I have to go through everything the whole process over again,” said Talia Montgomery-Jones, who started class on Wednesday.

“I spent $16,000 for this course and $14,000 in loans,” said Barbara Young, a student.

For students who were so close to finishing at school which promised to “secure your future” they don’t know where they stand.

“That’s a tragedy. We came here for almost a year to not have anything to show for it, so we don’t know what we’re going to do now,” said Adrienne Davis, who had two weeks left of the program.
