About 8pm, a 28-year-old woman was walking on Undercliffe Road, Earlwood, when she was threatened with a knife before her phone and backpack were stolen.
Half an hour later, a masked man entered a mixed business on McKern Street, Campsie, and threatened the attendant with a hammer, stealing cash and cigarettes.
The employee and his 18-month-old child weren’t injured.
In a third incident, about 9pm a man entered a convenience store on Burwood Road, Belmore, threatened a 28-year-old customer with a knife, and stole an employee’s phone and cigarettes.
The customer and attendant were not injured.
Police believe the robberies are linked.
They would like to speak to a man described as being of African appearance, between 180cm and 190cm tall, of solid build.
He was last seen wearing a surgical mask, black ‘Nike’ hooded jumper with the word ‘SWOOSH’ on the front, a white cap, red tracksuit pants, black gloves and dark Asics runners.
