Frankston police were quickly on the scene after reports of assaults and a theft in Frankston on Saturday night (17 June).
Investigators have been told a man was sitting at the Frankston train station with a woman at about 5.45pm when he was allegedly struck by a teenager.
The teen and his friend ran from the scene and were allegedly involved in the theft of a mobile phone and further assaults near Young St. The pair then fled the area.
Police arrived a short time later and arrested a 17-year-old boy from Noble Park and a 20-year-old man from Hallam.
Both have been interviewed in relation to the incident with the teen charged and bailed to appear at a Children’s Court at a later date to face assault and theft charges.
The Hallam man is expected to be charged on summons for similar offences.
