Closing arguments were completed Friday in the trial of a former Edmonton police officer accused of dangerous driving.

Douglas Kurtis Brown was on trial this week on four counts of dangerous driving causing bodily harm.

The judge will hand down a decision in the case on April 14.

Brown is accused of running a red light and slamming into a pickup truck last May, injuring four teenagers.

Brown was still an Edmonton police constable at that time but was off-duty at the time of the crash. He resigned from the force in September.

Along with the dangerous driving charges, Brown originally faced five counts of impaired driving causing bodily harm and one count of driving with a blood alcohol level over the legal limit.

All the impaired driving charges were dismissed Thursday after Provincial Court Judge Michael Allen found Brown's Charter rights were violated when police demanded a breath sample from him last spring. Officers didn't have reasonable and probable grounds to make that demand, the judge ruled.

The Crown also had one of the dangerous driving charges dismissed.

The Crown alleged Brown ran a red light and was speeding at the time of the crash.

But Brown has testified he was sober that night and told the court when he went through the intersection, the light was green, not red.
