A 19-year-old has been arrested on suspicion of murdering a student who was fatally stabbed in Manchester.
Luke O'Connor, 19, died in hospital after he was attacked in Wilmslow Road, Fallowfield, at about 2am on Wednesday.
A 19-year-old man was detained in the area on Friday evening and is being questioned.
Superintendent Helen Critchley, of City of Manchester South district, said: "The arrest of a 19-year-old suspect on Friday night is an important step in our investigation which is moving at pace.
"Since the tragic killing of Luke our investigation team has made significant progress as we do all we can to get justice for Luke's family who we are continuing to support at this devastating time.
"There are still a number of inquiries being conducted to establish what happened in the early hours of Wednesday, but what is clear is that this was a senseless and needless loss of a promising young life that has shocked our student community and we are doing all we can to support them too."
Mr O'Connor was a second year business management student at Manchester Metropolitan University and his family described him as "truly one of a kind, whose presence would light up any room".
In a statement on Thursday, they said: "Our hearts yearn for the loss of Luke; we are truly devastated by this tragedy.
"Luke was loved by so many people, and he knew how much he was loved in return.
"He loved the freedom of student living and studying and was loving life in Manchester.
"Luke was the youngest of three boys in our family and was a gentle giant with big hopes and dreams for the future.
"His biggest dream was to travel the world, but now Luke will never be able to fulfil that dream."
