While Nolan Gould and the rest of the "Modern Family" cast are enjoying their time in Sydney, Australia, Sarah Hyland has run into a bit of trouble Down Under.

The 23-year-old actress was seen leaving a party in tears on Tuesday night after allegedly being assaulted by a fan. 

We knew certain castmembers were being mobbed upon their arrival at the airport, but we never expected the fans' hype to turn dangerous.

Sarah was reportedly posing with fans outside the "Modern Family" party, hosted by Qantas, at The Sebel Pier One when the incident allegedly occurred.

A male fan allegedly asked Sarah to pose for a photo and then he reportedly grabbed her breast. 

Sarah reportedly pushed the man away and screamed, "Don't touch me there!" before her security team stepped in to question the fan and pass the matter over to the police, Daily Mail reports. (See the photos.) 

The actress explained her abrupt exit, following the incident, on Twitter.

Sorry to all the fans outside the #qantas event that I didn't get to say hi to but I had to leave due to an inappropriate touch of a fan

Her boyfriend, Matt Prokop, also came to her defense. 

To the asshole who assaulted Sarah tonight I hope to God you don't see next week.

All Sarah wanted to do tonight was say hi to the girls who were waiting outside one douche can ruin it for everyone. Goodnight.

"A man is assisting police with investigations following an alleged indecent assault of a woman yesterday. It is alleged the man indecently assaulted the 23-year-old woman near Hickson Road, The Rocks, at about 7.50pm. A 29-year-old man was arrested. Police are continuing their investigations," a spokesperson for the NSW Police told Daily Mail.

Sarah, along with the rest of the "Modern Family" cast, has been in Australia shooting scenes for a special episode.
