(CNN) A costume department employee who worked on the now-canceled Fox series "The Grinder" has accused actor Fred Savage of harassment, discrimination and assault and battery.

In a lawsuit filed on Wednesday, YoungJoo Hwang, a former costume designer on the series, alleges Savage created a hostile work environment and displayed aggressive and intimidating behavior on set, particularly toward women. She also alleges an instance of physical assault.

Savage called the allegations "completely without merit and absolutely untrue" in a statement provided to CNN.

"The Grinder" aired on Fox for one season, in 2015.
