A gang of around 10 youths allegedly carried out a racially motivated attack on a taxi driver, dragging him out of his vehicle and on to the road.
One of the gang also jumped on the bonnet and smashed the windscreen before a three-figure sum of cash was taken, police said.
The incident began when the group stepped out into the road and forced the vehicle to stop.
At least one of the youths managed to open the boot and steal an item.
Police said they wanted to speak to witnesses to the assault and robbery, which took place in West Pilton Place, Edinburgh.
The taxi was first approached close to the road's junction with Crewe Road Gardens at around 6.55pm on Sunday.
The suspects are described as male and female, aged between 14 and 20 years old.
The man who jumped on the taxi was white, tall, of slim build and wearing a red top.
The local residents' association, Trim and Friends of West Pilton, said it was part on an ongoing problem and has demanded a meeting with Holyrood's justice secretary, Michael Matheson.
