Cops shut street after assault at Aus Open

An indecent assault at the Australian Open shut down the street outside the tennis stadiums as police conducted "safety checks".

Police shut down Olympic Boulevard at Melbourne Park after a woman was indecently assaulted at the tennis by a man about 6.45pm on Wednesday.

Spectators were delayed from leaving Rod Laver Arena and Hisense arenas and were told the boulevard was closed "due to a safety issue".

"The prior and subsequent actions of the offender led to police conducting safety checks on Olympic Boulevard," police said in a statement on Thursday.

The checks were concluded about 10.30pm "with nil issues found".

No one was arrested and police say they are continuing to investigate the assault.
