Police have identified a third person in a video showing a French woman suffering a torrent of threatening, racist abuse on a Melbourne bus on Remembrance Day.

Detectives from the Transit and Public Safety Command Crime Investigation Unit have interviewed a 35-year-old Doncaster East man and released him pending further inquiries.

Last week, two other people - a man and a woman - involved in the hateful verbal attack, were spoken to by police.

Police are investigating the incident captured on video by stand-up comedian Mike Naynar, which shows passengers verbally abusing French tourist Fanny Desaintjores, 22, and her friends on board a bus in the city's southern suburbs.
