‘For the last two weeks I've been receiving messages off a group of fans, they have drowned my phone in messages, keeping me awake at night,’ Horan tweeted. ‘But the worst part is. They have been nothing but abusive. Saying things you wouldn't even believe about me and my family.’

‘And saying the worst things ever about my little nephew. Thank god I'm not the kind of person who thinks into stuff like this. But I just think it's crazy how we let people away with things like this. And the sad thing is, as I tweet this they are in the group chat laughing at me.’

After Niall then received messages of support from fans he added: ‘Don't worry about me. I’m the most carefree, laid back person around. But I'm just signalling it, because this shite is happening to others.’
