SYDNEY, March 28 (Xinhua) -- Reports of a person carrying a gun have disrupted the morning commute in Melbourne, Australia, on Thursday, with heavily armed police storming a train and forcing an evacuation.

The person of interest turned out to be a busker, carrying an instrument in a bag on his way to perform in the city.

"He was a local busker who was there to play an instrument in town," inspector Jacob Bugeja from Victoria police told reporters.

"There was a bag that the person was carrying and he had his tools to busk with him."

Police say that the man was doing breathing exercises on the train when a fellow passenger contacted police, believing the bag to be a rifle case.

Authorities halted the train at Flagstaff station and critical incident response officers conducted a sweep of the carriages before giving the all clear.

The operation took under one hour and police have apologized for the inconvenience, saying that the rapid response team acted quickly and performed well.
