Boy, 15, arrested after man slashed in head during alleged machete attack in Melbourne

A man allegedly attacked with a machete on a Melbourne street yesterday was left to bleed on the street while witnesses called for help.

A 15-year-old has been arrested after evading police for almost 16 hours following the alleged armed robbery which took place on Barkly Street in St Kilda around 9.15pm yesterday.

The pair demanded the 39-year-old victim's car keys and the male offender attacked him with a machete when he refused, police say.

The pair then fled the scene empty-handed.

The victim, who was allegedly slashed in the head, used his shirt to stop the bleeding as bystanders helped.

"The machete, it was huge, like literally like my elbow size. It was huge," one witness told 9News.

"There was a lot of blood because we just put on this t-shirt to avoid the blood, more bleeding."

The victim from St Albans was left with serious but non-life threatening injuries and is being treated in hospital.

Police today arrested the 15-year-old at Southern Cross Station about 12.30pm and took him into custody.

The female is yet to be found.

The witness told 9News the St Kilda area is a hotspot for similar crimes.

"It's quite unsafe, especially in this main road up here."

Anyone with information is urged to contact police or Crime Stoppers.
