Melbourne Incidents

Mernda Train Station Fatal Stabbing

Aidan Becker, 22, died at Mernda railway station on Friday evening after intervening in an alleged robbery and assault on a 14-year-old boy. The incident occurred at approximately 5:50 PM.

Police allege that four males approached the 14-year-old boy, attempting a robbery and initiating a physical assault. Mr. Becker, an off-duty security guard, intervened to protect the teenager, escorting him away from the immediate area. The four alleged assailants pursued them and attacked Mr. Becker with punches, kicks, and an edged weapon. He died at the scene. A machete was recovered nearby.

"He died a hero protecting a child." — Community sentiment echoed at a vigil attended by thousands.

Four teenagers have been charged in connection with Mr. Becker's death:

• A 16-year-old from Whittlesea
• Two 17-year-olds (one from Geelong, one from the City of Yarra)
• Mike Pikos, 18, from Mill Park

All four have been charged with murder and armed robbery. Court documents allege Mr. Pikos was armed with a machete during the alleged robbery of the 14-year-old's phone and power bank. Mr. Pikos appeared in Melbourne Magistrates Court and was remanded in custody.

A community vigil was held at Mernda station, attended by thousands. Mr. Becker's mother addressed the gathering.

The incident has led to increased patrols at Mernda station, including the deployment of a new state government violence reduction unit. Crime Statistics Agency Victoria data indicates a 50% increase in criminal incidents on public transport in the City of Whittlesea over the 12 months ending September 2025.
