Police are hunting for a knifeman who held a knife to a young girl while robbing her mother.
The man threatened the three-year-old in gardens by Bromley Parish Church.
The robbery, which took place last month, is being connected to a spate of thefts in the area.
Just days earlier three 17-year-old girls in Churchill Garden were approached late at night by a man asking for the time. The teenagers tried to ignore him but were followed and threatened with a knife.
The robber stole their phones and money before escaping towards Shortlands train station.
They describe the suspect as a six-foot-tall black male in his 20s, of slim build with short hair.
