The Texas trooper who arrested 28-year-old Sandra Bland last year was just fired, the Texas Department of Public Safety announced on Wednesday.

Former officer Brian Encinia, whose arrest of Bland was captured on dash cam footage last July, was indicted on perjury charges three months ago by a Waller County grand jury. He was found guilty of lying in his police report about the traffic stop. The video showed Encinia pull Bland over for an improper lane change and forcibly remove her from the car after she refused to put out a cigarette.

Three days after her arrest, Bland was found dead in a Waller County jail cell. The suspicious circumstances surrounding her death prompted protests across the country, and Bland's case has been referenced as an example of improper policing practices by civil rights advocates as well as Democratic presidential candidates Hillary Clinton and Sen. Bernie Sanders.

In a letter of termination, Texas Department of Public Safety Director Steve McCraw wrote "I have determined that you have not rebutted the charges set out in the statement of charges of January 28, 2016. No cause has been presented to alter my preliminary decision."

"Therefore, it is now my decision that you be discharged from the Texas Department of Public Safety effective at 5:00 p.m., upon the date you receive this letter, pursuant to the authority vested in me by Section 411.007, Government Code."

The "statement of charges" that McCraw mentioned refers to a series of allegations against Encinia regarding violations of police protocol during the July 10, 2015 traffic stop. Those include allegations that the officer "failed to remain courteous and tactful in the performance" and "prolonged the traffic stop beyond the time reasonably necessary to complete the tasks associated with the traffic infraction."

A lawyer for Encinia said that his client will appeal the Texas DPS decision, The Texas Tribune reports.
