When police officers have a hunch about something, they are often willing to go to extreme lengths to determine if that hunch will lead to an arrest. For one police officer in Texas, that meant going back to high school for four months.

School authorities and law enforcement believed one high school in the area had problems with drugs. Together, they came up with a scheme to determine if students were using and selling drugs at the school.

At the end of their investigation, 12 people were arrested on drug charges, including 10 current high school students.

Most of the parents bailed their students out of jail as soon as possible after the arrest. However, four students were still in jail more than 12 hours after the arrest.

Of the 10 students were arrested, five are juveniles and five are legal adults. One of the adults is a star on the football team, and he was arrested in the middle of class. After waiting four months to build an investigation, it's unclear why the police officers needed to interrupt class to arrest the student and lead him out in handcuffs.

Another student in class said he has known the football star since they played little league together as boys. The same student said that the police came into their classroom and said, "Sir, you're under arrest for selling marijuana to our undercover officer." One student said he was surprised there were so many students at the high school who were selling and using drugs.

A spokesperson for the school district said that the students who were arrested will likely be expelled. She didn't seem to consider the possibility that the students would not be convicted. And those students likely won't be the only ones expelled.

In an earlier effort to combat drug use, students are given random drug tests. Of the 100 drug tests that have been given since October, five students have failed their drug tests. They could also be facing expulsion.
