Comedian Chris Lilley has come under fire for reposting an old music clip called Squashed N***a via his Instagram account.

It came days after a controversial verdict was handed down over the death of Indigenous teenager Elijah Doughty in Western Australia.

A 56-year-old man, who cannot be named for legal reasons, ran over and killed the 14-year-old in Kalgoorlie in August last year.

Rallies, including a protest that brought Melbourne to a standstill on Friday, have been held around Australia after the man was acquitted of manslaughter and received a three-year sentence for the lesser charge of dangerous driving causing death.
