A man went on a stabbing rampage in downtown Sydney on Tuesday, killing one woman and wounding another before he was restrained by members of the public, police said, adding they were not treating it as a terrorist incident.
The 21-year-old man, who police did not name, was carrying a knife and a computer thumb drive containing information about deadly attacks in North America and New Zealand, police said, reports Reuters.
But he did not appear to be acting for any terrorist groups and the attack was not being treated as terrorism, police added.
A 21-year-old woman was found dead in an apartment building and a second woman, 41, was taken to hospital with a stab wound to her back. She was in stable condition, police said.
They did not say how the first woman died but said the man was responsible for both attacks. There was no apparent link between the two women.
Police were investigating a home about 32 km (20 miles) west of the city where the young man lived with his parents.
