Police are investigating a home invasion at Windsor.
About 1.20am (Friday 15 March 2019), police were called to Harris Street, after three males forced entry into a home and became involved in an altercation with a 22-year-old male occupant, who suffered a laceration to his back.
Three other occupants of the home, an adult male and female, and a female child, were uninjured.
The three offenders fled the scene after taking a sum of money. They were last seen running across a reserve in Harris Street.
