Government 'to urge social networks to crack down'

Culture Secretary Maria Miller is to challenge social media companies "pro-actively" police their sites and remove offensive and dangerous posts, the Daily Mail reports.

It follows the death of 15-year-old Tallulah Wilson who threw herself in front of a train in 2012 after sharing self-harm images with her 18,000 followers on the Tumblr social network.

The Culture Secretary will unveil a new measure at this week's Cabinet meeting, the report says, and plans to confront internet companies at a conference in the next few weeks.
