Anderson said no firearms were involved, but because there were concerns about some of the weapons reported to be involved members of the Armed Offenders Squad were called in.
He said an ambulance attended but no one was taken to hospital.
Anderson declined to reveal more details about the assault, the weapons used nor the description of the offender police are searching for.
