A Montgomery County Sheriff's Office deputy noticed the bus' broken light while it was driving through Splendora Sunday, the Houston Chronicle reported.
After pulling the bus over, the deputy brought his K-9 Ranger toward the bus and the dog immediately jumped inside the luggage area, alerting the deputy to possible drugs inside.
When looking inside the luggage area, the officer found 7,261 grams of cocaine, 3,355 grams of heroin and 89 grams of black tar heroin.
The bus driver, Juan Vorrath, 54, and passenger Ramiro Trevino, Jr., 29, were arrested and charged with possession of a controlled substance, money laundering and possession of a criminal instrument.
