'Modern Family' actress Sarah Hyland immediately left an event for the show after she was inappropriately grabbed by a male fan, E! Online reports. 

According to eyewitnesses, the overzealous fan grabbed the 23-year-old star's breast while she was politely posing for a picture with him outside of Sebel Pier One in Sydney, Australia. After he touched her, Hyland allegedly pushed the man and screamed, "Don't touch me there!"

Of course, security immediately got involved and the 29-year-old man was arrested, police confirm.

Hyland later took to Twitter to apologize to the fans she did not get to meet due to the incident, saying:

Meanwhile, her boyfriend, actor Matt Prokop, was more threatening in his tweet about the altercation, writing:

Yikes. No doubt this was a scary situation for the actress and her loved ones, and we're glad that she is okay.
