A teenager was arrested in Melbourne on Sunday after an allegedly stolen car drove along tram tracks on Flinders Street and struck a pedestrian at the Elizabeth Street intersection, blocks from Flinders Street Station while the city's marathon filled surrounding roads with runners.

Victoria Police said the 16-year-old boy was taken into custody "without incident" in Albert Park and would be interviewed. Authorities said the incident was not believed to be terrorism or a targeted attack.

Timeline police and witnesses describe

Multiple witnesses told the Australian Broadcasting Corporation they saw a white car moving fast and erratically along Flinders Street, Flinders Lane and Elizabeth Street from about 10:30 a.m. local time. Ambulance Victoria said crews were called just before 11 a.m. and transported one person to Royal Melbourne Hospital.

Police allege the teenager was driving the stolen vehicle on tram tracks on Flinders Street before hitting a pedestrian at Elizabeth Street. A woman from Southbank was treated for injuries police described as non-life-threatening.

Witnesses said the erratic driving unfolded as thousands of people participated in the Melbourne Marathon on a course that passes Flinders Street Station at the Swanston Street end. Several told the ABC the speeding car came within metres of the race route, though police have not said the vehicle entered the closed marathon corridor.

Emergency response in the CBD

Paramedics, multiple police units and other emergency services converged on the central business district intersection, one of Melbourne's busiest pedestrian and tram hubs. The ABC reported heavy police presence through mid-morning as investigators began piecing together the car's path from the inner city toward Albert Park.

Victoria Police have not released the teenager's name because he is a minor. Charges, if any, would be determined after the interview and review of CCTV and witness statements.

What riders and commuters should expect

Flinders Street is a core spine for Yarra Trams routes and pedestrian traffic between Federation Square, the station and the Yarra River. Even short police cordons there ripple across weekend events; marathon organizers and transport authorities often coordinate road closures, but unrelated vehicle incursions still raise safety reviews.

For Sunday shoppers and marathon spectators, the arrest ended the immediate threat, but the collision highlights how stolen-vehicle pursuits and joyriding incidents can intersect with major public gatherings in dense CBD grids.

Next steps for investigators

Police will likely trace how the car was stolen, whether others were in the vehicle, and whether tram-safety barriers or track design played any role. The injured pedestrian's condition will be updated by the hospital in line with privacy rules.

Anyone with dashcam or phone footage from Flinders and Elizabeth streets between 10:15 and 11 a.m. is routinely asked to contact Crime Stoppers or Victoria Police, though authorities have not yet issued a specific public appeal beyond general witness interviews conducted at the scene.
