"These residents of this house were not impressed at all shouting and screaming outside of their windows. This then created more of a commotion that turned into a very intense situation very quickly," he said.
"All of a sudden, a man came outside with a machete. The bare-chested man then proceeded to point and wave the machete around menacingly to students standing on the street."
The witness said around 10 to 15 officers turned up to arrest the man.
