The former partner of a man who died near a train station last year has been removed from court after threatening the accused killer.

Cody Frost, 36, faced the Melbourne Magistrates Court on Monday, charged with the murder of 24-year-old Marcus Rowley, who was stabbed after getting off a train in West Footscray on August 5 last year.

Police removed Mr Rowley's former partner from the court building after she called Frost a c---, a dog, threatened his mother and told him "you wait 'til you get out Cody Frost".

Four witnesses are giving evidence during Monday's committal hearing to determine if there's enough evidence for Mr Frost to stand trial.
