Man charged over brawl which left teen dead in Sydney

A man has been charged with affray after mass stabbing at a party in Ryde at the weekend, which left a 16-year-old boy dead.

The 20-year-old, from Ryde, had been under police guard at Westmead Hospital since Sunday morning and was today charged.

He was refused bail and is expected to appear at Parramatta Local Court tomorrow.

Police were called to the home in Ryde just after midnight on Sunday, following a fight among young partygoers that left six males and a female with stab wounds.

Aidan Smith, 16, was rushed to Westmead Hospital but died just a few hours later.

His sister penned an emotional tribute to the teen through a Facebook post, saying she "couldn't have asked for a better brother".

"Just wanted to say that I love you with all my heart Aidan and I'm so sorry this had to happen to you," she wrote.

"R.I.P my baby brother still cannot believe this has happened."
