Serbia's foreign ministry said Saturday that the detained Serbs were to appear before a judge.
The family of Bakari Henderson of Austin, Texas, identified him as the victim. His family said Henderson was in Greece working on a photo shoot to launch a clothing line. Bakari graduated from the University of Arizona in May with a business degree.
Greek police say the victim was beaten to death early Friday at a bar in Lagana. Officials haven't released a possible motive for the attack.
Greek police said Friday that a 34-year-old Greek and a 32-year-old British man of Serbian origin were arrested.
