Robbers told three schoolchildren they could 'do this the hard way or the easy way' before making off with their mobile phones and cash.

The victims, a 15-year-old girl and two boys aged 15 and 16, had just got off the N209 bus in Barnes last Sunday when they were surrounded by the gang of youths in Station Road.

One of the crooks put his hand in his pocket, leading the terrified youngsters to believe he was armed, as another made the chilling threat.

The five robbers, all men aged between 19 and 30, three of whom were wearing hoodies, made off towards Barnes High Street.
