Elderly homeless man bashed and carjacked in the city, man ambushed and stabbed in Pooraka, 41 killed when Russian airliner crash-lands and bursts into flames, warning on poisonous wild mushrooms.

A homeless, elderly man who claimed to have had critical medical equipment and a car stolen in an early morning robbery has been reported for making false claims.

Concerned good samaritans set up a gofundme campaign for Jack Walker, 70, following news of the theft.

However, on Tuesday afternoon police announced they had reported Mr Walker for making false claims about the disappearance of the car.

Mr Walker claimed he was unloading his car outside community housing on Wright St in Adelaide just before 11pm on Sunday when he was hit from behind.

He said the car was packed with equipment to help him breathe as well as insulin to keep his diabetes under control.

However an investigation by Eastern District detectives led police back to Mr Walker who was reported for making a false report.

At the time Mr Walker said he was in palliative care and only had months to live.

Police are still searching for the car, a blue 2005 Mitsubishi Verada sedan, with the licence plate XPU378.

The creator of the gofundme page has been made aware of the police action and is arranging for all donations to be refunded.
