Two stations packed with commuters were evacuated after the Olivia Rodrigo concert on Thursday, causing significant delays for weary concertgoers.
CCTV from the incident later revealed the incident was caused by a couple in a stairwell who may have accidentally triggered the sprinkler mechanism.
“It would appear that an amorous couple in a stairwell dislodged a sprinkler,” Minister for Transport Infrastructure of Victoria Danny Pearson told reporters on Wednesday.
“There was extensive flooding. Metro will be investigating these matters further and police are investigating.
“Perhaps a stairwell may not be an appropriate place to find yourself in after dinner.”
It was initially believed the flooding at Melbourne Central and Flagstaff stations was caused by an act of vandalism.
Police released CCTV and images of two people they believed could assist with their investigation.
It’s alleged the duo gained access to a stairwell about 10.40pm and damaged a water pipe and sprinkler.
Victoria Police said the offenders had fled the scene after the extensive flooding.
“The delays affected big crowds trying to get home from the Olivia Rodrigo concert at Rod Laver Arena,” police said at the time.
Investigations into the incident continue.
