One Direction’s Niall Horan has made a plea to fans to be careful what they throw at him whilst he is on stage.

The band were performing in Amsterdam on Wednesday night and a number of things were apparently thrown at the boys on stage which led Horan to tweet: “Can you limit what gets thrown on stage please! Coz somethin thrown at me tonight! Hit my knee! A lot of pain from it!

“Never wana sound like I'm complaining! But only having my operation 5 months ago, I still get a bit of pain and I'm very scared about it (sic).”

Niall was reportedly seen limping off the stage after the incident but it didn’t seem to sour him towards the fans with him later tweeting: “Amsterdam thank you for a great couple of shows! Appreciate you coming (sic).”
