For the fourth time this week, investigators say someone has set a fire inside a building at Eastern Kentucky University.
The latest fire broke out Thursday afternoon at Dupree hall. That's a dorm on campus.
Two of the previous fires were at that dorm. The other was started at the student center.
Thursday's fire was discovered in the trash bin. Someone lit some paper of fire, but luckily, it didn't spread.
Earlier this week, someone set a similar fire at Dupree Hall, as well as one in the stairwell.
A reward has been offered for information leading to an arrest of the arsonist.
Campus police and the state Fire Marshal are investigating.
