NSPCC says no need to be concerned about Momo
Some of you may have heard the false rumours about a character called Momo.
The character supposedly appears on social media and sets children dangerous "challenges".
But charities say there have been no reports of anybody receiving messages and say the whole thing is fake news and nothing to worry about.
Andy Burrows, Associate Head of Child Safety Online for charity the NSPCC says parents should talk to their kids if they have concerns.
