A man in his 30s has been arrested after an alleged stabbing homicide at a home in Sydney that police have described as "gruesome" and believe is linked to a drug deal gone wrong.
Authorities found the dead man, thought to be in his 50s, with stab wounds at a residence in Croydon Park just after 5pm on Monday, police said in a statement.
Police were called to the residence following a concern for welfare report.
Superintendent Christine McDonald said the 32-year-old suspect was taken to Burwood police station where he was assisting with inquiries.
Supt McDonald said police were "treating this as a homicide".
"This is a gruesome crime. The man's injuries are horrific," she told reporters near the crime scene late on Monday.
"We believe this is a drug deal gone horribly wrong.
"We don't believe it to be domestic-related. We don't believe it to be gang-related."
She said it was not yet known if the victim and the detained man knew each other, or whether anyone else was in the house at the time of the alleged killing.
Supt McDonald praised responding officers, who she said detained the suspect before he could leave the scene.
"When we arrived, the 32-year-old male who we now have in custody at Burwood police station was on scene," she said.
"We didn't give him any time to run away. We were here too quick."
