Detectives have charged a man with murder over the death of DJ Chris Bradley, also known as Dad Bod, at a party in Byron Bay on Christmas Day.
The incident was being treated as suspicious after the 28-year-old collapsed about 11.30pm at a Carlyle Street home.
A 24-year-old man was arrested in Ballina on Thursday morning, police said.
He was charged with murder at Ballina Police Station and is expected to appear in Lismore Local Court on Friday.
After the incident, Mr Bradley's little sister Maddie described him in a Facebook post as someone who lit up the room with his unique personality and laugh.
"To say the words I've lost my big brother it's gut wrenching," Ms Bradley wrote.
She also questioned: "Who could do such a horrible thing to such an amazing man?"
Mr Bradley was originally from Sydney and was known for his eclectic taste in music.
He started his company Atypical Entertainment in Byron Bay with close friends, according to a biography on its website, and listed his main passion as house/techno/dance music.
