Niall Horan has warned his fans about their behaviour during his live shows.

The former One Direction star said that he nearly had to cancel two gigs in one week due to the behaviour of some members of the crowd. During a show this week in Mexico, Horan said on stage that he might have to stop playing over crowd safety fears. He stopped the show in Mexico City's Pepsi Centre on Friday and said: "Everyone needs to look after each other, or we're going to have to cancel the show. Everyone look out for each other, OK?" Horan also took to Twitter to express his concern. He wrote: https://twitter.com/NiallOfficial/status/1017972645130833921 Horan then followed up this tweeted with: "I mean have ya heard my album Hahahahah, it's not meant to look like a rave out there." No, Niall. It's not. This comes after reports that a fan fainted during Horan's Argentina show, with Twitter users saying that the event "got messy." The Mullingar lad will be travelling around South and North America until September performing his debut album, Flicker.  He is expected to return home once that tour ends to focus on writing and recording his second album.
