Emergency services at the Torcher Parade on Union Street in April
A jury has been shown CCTV footage of a motorbike ploughing into pedestrians during a street parade.
The video clips were shown during the trial of a teenager accused of culpably and recklessly riding on a motorcycle at excessive speeds.
Graeme Hunter, 18, from Aberdeen, is also accused of riding it in an erratic manner and kicking and punching pedestrians.
The trial at Aberdeen Sheriff Court continues.
Seven pedestrians were injured when the motorbike collided with them during Aberdeen's student Torcher Parade on Union Street in April.
The court heard Hunter was sandwiched between two other youths when the bike left the road.
Leading the jury through the CCTV footage, Grampian Police's Pc David Patterson explained how pedestrians were "kicked" and "punched" by the passengers as they tried to stop the youths.
Pc Patterson said: "It appears they were waving to the police car going down Union Street. The bike becomes stationery and a pedestrian comes from the footpath to stop the bike and is quite violently kicked.
"It is not clear which one, but appears to be the male in the middle.
"The passengers were gesticulating on the bike in a triumphant manner."
The court heard how the bike veered from carriageway to carriageway and was driven up the wrong side of the road.
The jury then saw footage of the Honda 125 bike striking the side of a yellow van and gasped when the bike ploughed into pedestrians on the pavement.
PC Patterson said: "It hits the side of the car then hits the pedestrians.
"The police were at the scene very quickly because they were there for the Torcher Parade.
"There appears to be one person trapped under the bike."
Defence solicitor, Ian McGregor, described the collision scene shown to the jury as "horrific".
But he argued that Hunter had no control over the direction of the bike or the speed in which it was driven.
Mr McGregor asked: "Did the person driving it have control and no-one else?"
Mr Patterson replied: "Yes."
He also suggest that it was unclear whether one of the passengers had punched or kicked a pedestrian in the footage.
But the officer replied: "It looked like a kick."
Closing speeches in the trial are due to be heard on Wednesday afternoon, afterwhich the jury will be sent to consider its verdict.
