A Willmott man allegedly doused a woman with fuel while she was in front of her six-year-old daughter in western Sydney on Friday.
Police alleged Terry James Huntley, 33, of Willmot, threw the fluid on his partner and threatened her with a cigarette lighter about 4.30pm.
The woman called the police and Mr Huntley was arrested at the scene.
Officers said neither the victim nor her daughter were injured, although they were left shaken by the incident.
Mr Huntley faced Parramatta Bail Court on Saturday, charged with maliciously throwing an explosive liquid with the intent to do grievous bodily harm and intimidation over the incident, and later with assaulting a police officer at Mount Druitt police station.
Police alleged Mr Huntley was having paperwork explained to him at the station when he attacked a female senior constable.
She was left with superficial grazes to her neck and was treated at the station.
Mr Huntley did not apply for bail, which was formally refused.
He was due to face Campbelltown Local Court on January 29.
