Security issues have again made news here, with police Sunday searching for a man who sexually assaulted a 10-year-old girl as she watched Andy Murray during a practice session.
Melbourne media report that the suspect approached the girl, separated temporarily from her family, and assaulted her before fleeing.
Police are reviewing security camera footage for possible images of the suspect, described as around 50 and wearing a red t-shirt.
It is the second incident of its kind in recent editions after a boy was dragged into a toilet on the grounds and sexually assaulted.
In 2009, security officials were on alert after reported incidents of “upskirting” with hidden cameras.
Police have revealed that Croatians ejected from the grounds earlier in the week for Nazi salutes and trying to cause mayhem are linked to a group of right-wing extremist football supporters in Zagreb.
