TX- Grand jury removes prosecutors so jurors could hear from a witness about potentially faulty DWI tests.

Houston, TX - There are new questions about just what a grand jury is investigating after prosecutors were thrown out of the grand jury room.   

In an incredibly rare move this week, the foreperson of a Harris County Grand Jury asked a bailiff to remove prosecutors so jurors could hear from a witness on their own about potentially faulty DWI tests.
 
13 Undercover first raised questions about the accuracy of the Houston Police Department's so-called BAT vans, but now it's the investigation into how those problems were handled that's causing controversy.

For months, some of the people closest to HPD's breath testing vans have told you and us that the vans are unreliable -- meaning the roadside tests they do on alleged drunk drivers may not be accurate.

Now the controversy has spilled over into a grand jury investigation, and it's become so heated that a prosecutor working for Harris Co. District Attorney Pat Lykos was thrown out of the grand jury room earlier this week under the threat of arrest.
