A baseball bat-wielding motorist attacked a car on a notorious stretch of busy road after a crash.
Police are asking for dashcam footage to help trace the man who responded to a “minor” A9 bump by leaving his car and smashing up the vehicle behind him with a baseball bat.
An investigation has been launched following the incident on Sunday afternoon and officers are asking for passing motorists to help with enquiries, although say they are following positive leads.
The incident happened in broad daylight and in the middle of live traffic, just south of Dunkeld on the southbound side of the carriageway.
Police say at around 1.45pm, a grey Vauxhall Astra pulled in front of a red Mercedes A-Class and braked sharply, causing the collision.
The driver of the Astra left his vehicle and clubbed the Mercedes with the baseball bat several times, before the Mercedes driver was able to escape.
Most of the stretch of road is currently subject to a 40mph speed limit due to Transport Scotland’s carriageway dualling project.
Traffic cones begin to close off the overtaking lane of the southbound dual carriageway around a mile south of Dunkeld and motorists in the right hand lane are given around 1,000 yards to merge into single file.
The astonishing show of aggression happened in a live lane of the A9, which was busy with weekend traffic at the time.
The Astra driver was described to officers as being a white man with a tanned complexion, about 5ft 9in and of stocky build with very short dark hair and facial stubble.
At the time of the attack, he was wearing a grey, short sleeved t-shirt and blue jeans.
A police spokesperson said: “We are investigating an incident which took place about 1:45pm on Sunday 23rd August on the southbound A9, about 5 miles north of Bankfoot.
“A grey Vauxhall Astra pulled in front of a red Mercedes A-class and braked suddenly, leading to a minor collision. The driver of the Astra then got out of his car and hit the Mercedes with a baseball bat or similar item a number of times before the Mercedes driver was able to drive away.
“While we are following positive lines of enquiry, we would still like to hear from anyone who witnessed this incident, or may have dashcam footage of all or part of it.
