SYDNEY -- A second man has been arrested after an unprovoked "bottle" attack in southwest Sydney that left a 45-year-old man with a fatal throat wound.
The victim was attacked with a broken bottle outside a block of units on Garrong Road at Lakemba while having a conversation with his hearing-impaired father around 12.30am Sunday, police believe.
The man sustained a fatal neck wound during the altercation in what police have described as a "malicious and cowardly" attack.
Emergency services attended the address following the assault but the victim died at the scene.
Police initially arrested a 48-year-old man after riot police executed a number of search warrants on properties in the area. He is expected to be released shortly.
On Sunday afternoon, police confirmed that a 24-year-old man had also been arrested in connection with the death. He is currently assisting officers with their inquiries.
Earlier, Detective Superintendent Michael McLean told reporters police were treating the incident as a homicide.
He said police believed the victim was attacked, likely with a bottle, due to a dispute over noise.
"The incident has all occurred within a very short period of time," Detective Superintenent McLean said.
"This attacker has approached those two people and suggested that the conversation was too loud, there were some undertakings given to quieten down and in fact move on, but unfortunately that attack occurred and resulted in the very senseless and unnecessary death of this man.
"A man, relatively defenseless, has lost his life today at the hands of another person in an unprovoked manner."Suggest a correction
