The 'good news' story from London's Grenfell Tower fire you shouldn't be sharing.

When 79 people are killed after a fire rages through their apartment complex – a place where people are entitled to feel safe and secure – it’s only natural for people to seek out whatever sliver of ‘positive’ stories of escape they can find.

So when news broke that 12 days after the tragedy, a baby had been found alive in the burnt-out remains of the Grenfell Tower, the story went viral.

The story claimed the baby had survived the blaze, and had been found on the sixteenth floor of the tower.

A link to the story - which appeared on a site called Metro-uk, which has no relation to the real Metro.co.uk - was shared under the guise of 'breaking news'.

The article included quotes from real people, like London Mayor Sadiq Khan and emergency workers who had been involved in the rescue operation.

So a baby has been found alive on the 16th floor of Grenfell Tower. I did say there were probably still some survivors. #GrenfellTower

But it has been revealed the story is a cruel hoax, posted by a 'fake news' outlet which is infamous for sharing other fabricated stories in the past.

Readers were horrified that such a hopeful story could have been shared for the simple purpose of tricking the public.

How low can you get. There's a fake story going around about a baby being rescued from Grenfell Tower after 12 days.

Sadly, the rise of false, shareable content is nothing new: in the wake of tragedies like the Manchester attack and the recent terrorist events in London, many shared links and images of people missing in the attacks.

Some of the images spread online were stolen, with one belonging to a Melbourne girl who was at primary school at the time of the attack on an Ariana Grande's concert.

Readers are being urged to notify Facebook of the fake story if it appears in their feeds.
