A suspect is in custody after police believe he broke into the Tulsa County Courthouse. 

Authorities say the man broke through two glass doors and went to a second set of doors by a jury room and broke through those. While inside the courthouse the suspect pulled a fire alarm and called police on himself, officers said. 

The suspect told investigators that people were chasing him. Authorities are investigating. 

Officials said the clean-up will be ongoing through the night and court will not be impacted.
