The home secretary delivered a statement to the House of Commons after visiting the scene in Southport where several children were stabbed at a dance workshop on Monday. Yvette Cooper told MPs misinformation had already spread online about the identity of the attacker and warned 'those who do this for their own purposes risk undermining a crucial criminal investigation'. Misinformation has been spread on social media platforms by sources ranging from far-right activists to fake news websites. The police have only revealed that the attacker is a 17-year-old male. Three children were killed in the attack and several others and two adults are being treated in hospital
