A woman has appeared in court following an incident at Glenfield on Saturday night where two people suffered injuries.
Emergency services were called to Dobu Place just before 5.30pm and found a man with a slash wound to his upper left leg, while a woman had a minor laceration to her head.
The 44-year-old man and his 47-year-old partner were taken to Campbelltown Hospital for treatment, while officers from Campbelltown City Police Area Command established a crime scene.
Three women were arrested a short time later and taken to Campbelltown Police Station; however, two have since been released pending further inquiries.
A third woman, aged 36, was held overnight in police custody before being charged with wounding with intent to cause grievous bodily harm.
She was refused bail to appear in Parramatta Bail Court on Sunday.
An improvised weapon was seized at the scene and has been taken for forensic examination.
Detectives investigating the stabbing of a 21 year old man in a car park adjacent to a sporting field at Eschol Park last week have arrested and charged a man and woman.
The first to be arrested was an 18-year-old woman at Ruse, who was charged with wounding a person with intent to cause grievous bodily harm and tampering with evidence.
At a home in Rosemeadow police seized a machete, among other items.
Police also executed a search warrant at a home in Ambarvale where they seized a number of items.
A 19-year-old man was also arrested in those premises and charged with wounding a person with intent to cause grievous bodily harm, and affray.
Both were refused bail and remanded in custody to reappear in Campbelltown Court on June 30.
