A man in Darwin has allegedly thrown a full metal rubbish bin from an apartment tower onto a moving car 25 floors below, shocking a driver who emerged unharmed, police say.

The bin smashed the woman's windscreen and dented the bonnet, scattering pizza scraps and glass bottles across the central Darwin street last night, Duty Superintendent Helen Braam told the ABC.

"Driving along and suddenly being struck by an object," she said.

"[The driver] was very unhappy about the damage to her vehicle and was in a bit of a state of shock.

"It wasn't a large bin but it was full of rubbish at the time. There was quite a lot of sundry items like old pizzas and glass bottles."

When police were called to the Mantra Pandanus apartment on Knuckey Street about 10:00pm they were approached by "a number of witnesses that had observed the apartment where the bin had come from", Duty Superintendent Braam said.

Police arrested a 31-year-old man in the apartment and charged him with endangering the occupant of a vehicle and damage to property.

The 60-year-old female driver was uninjured, police say.
