COCONUT CREEK, Fla. -- A security guard at a South Florida college was caught on surveillance video entering a professor's office and stealing an exam from his desk, but the school failed to report the incident to the state, Local 10's Jeff Weinsier reported Tuesday.

Ahmed Fuad Khan, a professor at Broward Community College's north campus, has watched the video about 100 times and said it makes him sick to his stomach each time. In the video, a campus security officer, still wearing his BCC embroidered security shirt, enters Khan's locked office and takes an exam from the professor's desk.

"Unbelievable that one of our own, who is supposed to protect us, is committing such a crime," Khan said.

Khan said it happened four months ago after hours.

The video shows Davidson Jean Baptiste talking on a cell phone and rummaging through a file cabinet. He then searches Khan's desk, finds an exam, picks it up and leaves the office.

"He takes his time," Khan said. "He's not afraid, as you can see on the video."

The professor said he thinks Baptiste went to make a copy. About 10 minutes later, Baptiste returned and meticulously placed everything back on the desk the way it was.

"I wouldn't have know if I didn't see the video," Khan said.

So why did Khan set up a hidden camera to begin with?

According to a police report, Khan said he became suspicious when one of his students who was doing poorly in class passed a test with flying colors. That student is married to Baptiste.

When Khan showed the video to BCC administration, the student was removed from his class and Baptiste was eventually fired. Local 10 confronted Baptiste to talk to him about the incident, but he wouldn't comment.

"I believe he should be prosecuted," Khan said. "He should have a record. People should know what he did."

Coconut Creek police were called and a report was filed, but according to a police department spokesman, BCC didn't want to press charges.

Security officers are licensed by the state. According to the Florida Department of Agriculture, BCC never contacted the state to report the incident, which is a violation of the guard's state license.

Dr. Barbara Bryan, the provost for BCC's north campus, refused comment. BCC President J. David Armstrong said he didn't want to "say anything until we have all the information."

Meanwhile, Khan, who has been with BCC for 19 years, was formally reprimanded for confronting the student married to Baptiste.

"I always believe in doing the right thing," Khan said.

Local 10 contacted the Department of Agriculture, which has launched a formal investigation that could result in Baptiste's license being revoked.
