A man armed with an axe confronted a gang of youths in the middle of a busy street in broad daylight.
The man, with a small hatchet clasped by his side, was filmed in the Parkhead area of Glasgow on December 18.
Despite the threat of serious violence, drivers pass the scene with barely a second glance.
At one point, a woman with a child in a pushchair even crosses the road nearby.
The man filming, who asked to remain anonymous, comically describes the fearsome scene as "gymnastics", with the two arguing parties charging backwards and forwards in tandem.
