Mr Pledger, 30, is facing four charges for allegedly assaulting a woman, authorities say.

He had been granted bail on Monday to undergo a court-ordered medical assessment, on the strict condition that he return the following day.

But when he failed to show up in court, police appealed for public information and issued an arrest warrant.

The actor was detained in Melbourne on Thursday, Victoria Police said. They did not offer further details.

His manager, Craig McMahon, told the Sydney Morning Herald newspaper he had not been in contact with his client this week but that he had been shocked by the assault allegations.

He also said that Mr Pledger had been struggling with mental health issues.

The actor has appeared on Australian television shows for over two decades.

In 2016, he joined the cast of Home and Away where he played Mason Morgan for three years.

Prior to that, he appeared on the popular soap opera Neighbours, as well as TV shows Silversun and CrashBurn.
