AUSTIN (KXAN) — The man who boarded an AISD bus and claimed to be with the DEA and CIA has been taken into custody. The AISD police chief says the man, John Mikel Humphries, 29, is in the Travis County Jail.

“Many thanks to all the citizens who called in tips leading to identification,” Chief Eric Mendez said in a tweet.

Humphries was seen at Murchison Middle School on Tuesday, taking photos of students as they used the crosswalk.

AISD police say Humphries, later that afternoon, pulled over an AISD school bus after the driver dropped off the one remaining student.

Police said the man drove a black Chevrolet Tahoe, which looks similar to many unmarked police vehicles, and flashed the school bus with his headlights. At first, the bus driver opened her door at a red light and spoke with the man while he was seated in his vehicle. Authorities say Humphries asked the driver about her route.

After she dropped off an Anderson High student, Humphries boarded the bus and asked about the route again. He wore black military-style pants, an orange shirt and had a holstered handgun. The bus driver said the man said, “I am getting paid by the city. I am not a vigilante or an a**hole.” When asked for his law enforcement credentials, he got off the bus.

Cameras on the bus captured the moment, but were too blurry to see his license plate number. Chief Mendez said police would patrol the bus routes during operating hours until the suspect was found.

“In my 26-year career… I’ve never seen someone as brazen as stopping a school bus and entering a school bus here in Austin,” the chief said. “Thankfully, no students were on board.”

In 2011 and 2012, Humphries was charged with assault causing injury–family violence. He has previously been accused of a variety of crimes, including failure to stop and render aid, public intoxication and criminal trespass.
