Two more people have been arrested over an incident in Hamilton where hundreds of litres of milk were emptied from a tanker and the windscreen smashed.
Videos circulating online show milk pouring out of the tanker on Orini Rd, as well as people surrounding the vehicle as it appears the driver tries to keep his door closed.
A significant amount of milk was emptied from the tanker and a hammer was used to smash the windscreen during the incident, which happened on March 19, police said.
The driver of the tanker was not injured.
An 18-year-old male was arrested and charged with wilful damage, disorderly behaviour likely to cause violence, and possession of an offensive weapon last month.
One person told the Herald the tanker hit two cars and tried to drive off.
"The event had two groups of people attending. One group attacked the tanker while the other crew defended the tanker. The attacking group is not part of the normal car scene in Hamilton."
A young woman was reportedly injured as she tried to protect the tanker driver.
Another girl was reportedly shoved into nearby scrub and was stood on, the person said.
"The milk discharge was done by someone in the video who is clearly visible, this person has since been dealt to by his father.
"The tanker driver is a little shaken but unharmed thanks to the efforts of the local Hamilton car crew and their actions defending the driver and doing their best to stop the attack."
