Aidan Smith died after being stabbed at a party in Ryde on Sunday. Credit:Facebook Police are keen to speak to one male involved in the brawl, who was also injured during the fight. Earlier reports suggested that, in the lead-up to his death, Aidan and a group of friends made their way to the halfway house on Victoria Road about midnight, looking for a challenge after hearing someone at the party wanted to fight. But Ms Smith dismissed the claim. "He didn't go to the house 'knowing there was a challenge'," she said, paraphrasing an earlier report.

"Sadly the boy critically injured is my son ... He passed this morning ... RIP Aidan," he posted on Facebook. A man is taken to hospital after the stabbing at a party in Ryde.

The 16-year-old was discharged and the 20-year-old was in a serious, but stable condition on Sunday. Three boys, two aged 16 and one aged 17, and a woman aged 18 were all taken with lacerations to Royal North Shore Hospital but were later discharged.

Ryde Local Area Command Superintendent John Duncan said police were met with a "confronting" scene at the house in the quiet neighbourhood. "At this stage of our inquiries we are trying to establish why the party turned violent," Superintendent Duncan said. It is understood 50 people attended the party and no gatecrashers were involved. He said there was no evidence of gang involvement.A number of people were handcuffed and questioned by police at the party but no arrests had been made by Sunday evening. Aidan's older sister posted a tribute to her brother on Facebook on Sunday morning: "Just wanted to say that I love you with all my heart Aidan and I'm so sorry this had to happen to you. "I couldn't have asked for a better brother, through everything we went through you were always there for me and I'll always be your number 1 supporter.

"R.I.P my baby brother 💕 still cannot believe this has happened," she posted. Shocked neighbour Graham Kilby said the death and multiple stabbings were completely at odds with the area. Mr Kilby, who lives beside the scene, said a young man had visited him on Friday, "politely" informing him of a party the next evening. The first he saw of any trouble were flashing lights outside his home between 12.30am and 1am. "It wasn't rowdy, they were fine. There was music but nothing out of the ordinary. That's why it's so surprising.

"The funny thing is, they were that polite," he said of "upset" partygoers after the incident. "Girls from the party were asking for water – it's like chalk and cheese. It's so much of a shock to find out a young fella has been killed." He said the scene of the multiple stabbing was a council-owned "halfway house" and that its residents stayed for about a month at a time. Late on Sunday morning, a pair of pants lay on the front lawn alongside a forensic sign, while forensics officers were seen gathering evidence from the back garden and the area surrounding the house. Police scoured the blood-stained pavement of the busy six-lane thoroughfare.

A nearby bus stop was also cordoned off after police found what is believed to be a discarded bloodied piece of clothing on the pavement. Shocked and grieving friends of Aidan - known affectionately as "Smithy" - posted of their loss on Facebook: "Rest in peace Aidan. Didn't deserve any of this, fly high up there." "[You] were truly such a positive light everywhere you went, you didn't deserve this."
