Two robbers on a moped threatened a couple and a baby with a knife during a broad daylight robbery in Chelsea .
Police are appealing for witnesses to come forward after the terrified parents handed over their watches during the robbery in Sprimont Place.
Footage has been released of the moment the riders were seen driving away from the scene, with screams heard in the background.
The crime occurred on Saturday (September 2) at 3.30pm, when the 31-year-old woman and 32-year-old man were approached by two men on a moped.
