A brazen moped gang has been jailed for a string of bold "professional, planned and organised" high profile raids and a "shocking" attempted robbery where a mother was threatened with her three-year-old being snatched away from her.

In what the judge described as an "exceptionally serious and shocking attempted robbery" which had "a degree of planning", four gang members were caught on CCTV targeting a woman with a young child in broad daylight in Sandpits Road, Richmond.

Pheobe Ruele was walking hand-in-hand with her son whom she had just picked up from nursery when two motorcycles road past, pulled into the road and waited for her on June 21 last year.

The court heard that John McFadyen, 24, grabbed her arm hard enough to leave finger-mark bruises and told her: "Give me your rings. I'm going to hurt your child and take him away."

Footage shows the "terrified" woman can be seen dragging her child into the road before builders chase the gang away, brandishing scaffolding poles.

The judge noted that "fortunately there were no cars in the vicinity at that moment" but added that Ms Ruele is now "afraid for her children's safety when she takes them to and from school".

The defendants, who are aged between 19 and 36, also used their mopeds to block traffic before taking an angle grinder to cameras rigged up to capture the Oxford versus Cambridge boat race on March 22 last year.

Although their first attempt on Putney Bridge was interrupted by off-duty police officer Steven Wagstaff, a highly-specialised BBC camera worth an estimated £180,000 was stolen from Lonsdale Road by Barnes Bridge just an hour later.
