It was in the middle of the day on November 30 that four young people behaved messily on a bus on line 19. Among other things, the emergency brake was pulled, something that made the driver see red.

Two of the four left the bus shortly afterwards.

Knives cut hard

The two who remained resented the driver, who said no, and attacked him.

The man was severely stabbed in the torso.

A passenger who tried to intervene was also stabbed before the two disappeared from the scene.

It soon became clear that there were great opportunities to identify the boys, both through witness statements and the bus' surveillance cameras.

Attempted murder

So now three teenage divorces have been arrested.

The 17-year-old who is suspected of being the knife man was arrested in early December.

The criminal classifications are attempted murder of the driver and aggravated assault of the passenger who was stabbed in the leg.

Prosecution is expected within a couple of weeks.
