A number of people forced entry into a home by smashing a window, before demanding money and stealing a motorcycle.
One of the home occupants was assaulted causing injuries to his head.
Shortly after a security officer spotted the group pushing the motorcycle down the road.
They approached her vehicle and hit the drivers side window with a small axe which smashed through the window, narrowly missing the driver as it landed next to her.
The group fled the area and abandoned the motorcycle.
