A man was stabbed and two others were injured during a large fight at an Adelaide bus station last night.
Police received calls from alarmed members of the public reporting "a large group of people fighting" about 7:50pm at the Tea Tree Plaza bus interchange in Modbury.
A 30-year-old man was taken to the Royal Adelaide Hospital with a stab wound to his chest, but his injuries are not believed to be life-threatening.
Two men, aged 19 and 24, suffered minor injuries and were taken to the Modbury and Lyell McEwin hospitals.
A 21-year-old Modbury woman was arrested at the scene and was charged with affray and aggravated assault causing harm.
"She's been bailed to appear in the Elizabeth Magistrates Court on the first of March," Senior Constable Kristina Phillipson said.
"Police are continuing to investigate that altercation."
Local authorities have said the bus interchange was a known trouble-spot in off-peak hours.
Tea Tree Gully deputy mayor Lucas Jones said the latest incident was further proof of the need for addition security and CCTV.
"I think that needs to be extended to have security guards out here all the time," he said.
"Thousands of people from the north-east use this interchange every single day."
State MP Frances Bedford agreed, saying "we need a presence here like a station master or an interchange person".
Anyone who witnessed the incident, but had not yet spoken to the police, was urged to contact Crime Stoppers on 1800 333 000.
Meanwhile, police are looking for two men who robbed a woman at knifepoint in her southern suburbs home on Friday morning.
The woman was asleep when two men entered her home on Carruth Road in Torrens Park.
Police said the men got in through a side gate about 7:45am and ransacked the house, stealing electronic items and jewellery before fleeing in a blue Toyota RAV4.
The car, "with a possible registration of SB990B", was last seen travelling west on Barrelder Road before turning left to travel south on Belair Road.
The woman was not injured and police have appealed to anyone who may have dash cam footage of the car on Belair, Barrelder, Carruth and Goodwood roads and O'Neil street to contact Crime Stoppers.
