Random attacks The male suspect, described as Turkish or Middle Eastern, was arrested in a red Hyundai by unarmed officers this morning.The suspect was arrested after he pulled up in the car outside his home in Haringey, north London.The victims were both male and female and of different ethnicities, he said.
They were waiting for him when he pulled up in the car.
They were also a cross-section in terms of ethnicity."It has been a terrible morning and the investigation goes on."Arrest Around 60 or 70 officers are working on the case and forensic teams are at each stabbing scene.
Mr O'Brien said police had received information about the suspect and had gone to his house.
Police have defended shooting Jerry Sourian, 23, and inadvertently injuring three elderly women, instead of using tasers to diffuse the situation outside Westfield shopping centre at Hornsby in north-west Sydney.
Another witness, David Allars, wrote on Facebook: 'So was sitting having a coffee at Hornsby mall when I heard 3 shots go off about 50m from where I was and all these people started screaming and running.
The Metropolitan Police and my heart and prayers go out to his family."At 8.20am we were called to the first stabbing and that man went to hospital where he is in a serious but stable condition."Forty-five minutes later other calls came in to other stabbings in the area.One of those people stabbed has died."The stabbings were random and there appears to be no link between the victims.He did not put up a struggle and police recovered a knife. Mr O'Brien said his officers would be investigating whether there was a link between the random attacks and the killing of Turkish Cypriot shopkeeper Mr Fahri at his grocer in the Green Lanes area on Wednesday.He said: "It will be a major line of inquiry."He added: "This morning we are dealing with the tragic death of a man who has been stabbed.A man arrested over a stabbing rampage which left one person dead and five others seriously injured has 'a history of mental illness', police said.Chief Superintendent Simon O'Brien said the attacks in north London appeared to have been "a completely random cross-section".
