Police are investigating criminal damage resulting in the evacuation of two CBD railway stations last night.
It is believed that two unknown offenders gained access to a stairwell connecting platforms at Melbourne Central station and damaged a fire sprinkler about 10.40pm.
The offenders fled the scene.
The damage to the sprinkler caused extensive flooding to several platforms, which resulted in an automated evacuation of both Melbourne Central and Flagstaff Railway stations.
The flooding and evacuation of the stations had a flow on effect to Melbourne's underground rail network, causing significant delays.
The delays effected big crowds trying to get home from the Oliva Rodrigo concert at Rod Laver Arena.
At this stage it is unclear if Miss Rodrigo planned to get home via train or limousine.
The investigation remains ongoing.
Anyone with information is urged to contact Crime Stoppers on 1800 333 000 or submit a confidential report online at www.crimestoppersvic.com.au
