The brutal dumping of an American hospital patient from her wheelchair has sparked outrage and the sacking of three officials.

Video taken outside Howard University in Washington DC has been released showing how a campus police officer wheeled the female patient out from the university hospital in the lead-up the incident, reports The Washington Post .

Her legs are flung in the air when the wheelchair stops sharply. The officer and a colleague watch as she tumbles to the wet sidewalk near a bus stop.

Footage shows a third university official throwing up her gloved hand as she tells her colleagues to "leave her there".

Bystanders can be heard voicing their concern about the woman.

Two campus cops and their supervisor have been fired as a result of the shocking incident.

Gabriel Adegoke, president of the Metropolitan Campus Police Officers Union, which represents the officers, said the female patient had become agitated.
