Nearly half (43%) of adults in the capital are very or quite worried about the welfare of a child in their neighbourhood.
A survey by Action for Children also found the same number of people didn't tell anyone fearing they would cause trouble for the people involved, or themselves, if they were mistaken.

Thousands of cyclists have crossed the start line for the 40th anniversary London to Brighton bike ride in support of the British Heart Foundation.
More than 28,000 people are thought to be taking part in the 54-mile cycle ride, which is the largest of its kind in Europe.

Scientists in London have overseen an international trial of a new treatment that could be available as a game-changing new treatment for skin cancer within 12 months.

Results from a Phase III trial involving patients with aggressive, inoperable forms of the disease showed the therapy can eradicate tumours and halt their growth.
The trial was led by Professor Kevin Harrington at the Institute of Cancer Research.
The Royal London Hospital and Newham University Hospital have been declared inadequate by the Care Quality Commission.Read the full story ›
