Attempted murder charge over knife frenzy

A man has been charged with attempted murder after over a knife-wielding rampage at a Melbourne train station which injured five women.

Three victims remain in The Alfred Hospital in stable conditions after they were attacked in the bizarre daylight ambush at Glenhuntly train station about 11am on Sunday.

A 47-year-old Carnegie man has been charged with attempted murder, intentionally causing serious injury, affray and making threats to kill.

Four women, including one in her 80s, were pushed off the platform onto the tracks in the attack.

It will also be alleged the man initially stabbed a woman's handbag and his knife broke in half.

Witness Annabelle Jiles told the Seven Network the woman in her 80s was standing on her platform with a trolley.

"And he just walked down and hit her in the face," she said.

Sergeant Jason Venturoni told reporters at the scene the incident could have been much worse.

"Very lucky that no one was more seriously injured or killed. It was a very serious incident and could have resulted in the death of these ladies," he said.

The woman in her 80s suffered head and leg injuries while another woman in her 60s suffered facial injuries, an Ambulance Victoria spokesman told AAP.

The man has been remanded in custody to appear in Melbourne Magistrates' Court on Monday.
