Niall Horan has warned One Direction fans to stop chasing their cars.

The 21-year-old singer has begged his admirers to stop risking their lives by pursuing him and fellow band members Liam Payne, Louis Tomlinson and Harry Styles in high-speed road chases.

Airing his frustration prior to their 'On The Road Again Tour' show in Minneapolis, Minnesota on Sunday (26.07.15), he told his 22.8 million Twitter followers: ''Guys, I've said it before and I'll say it again

Ya can't keep driving this crazy, ya gotta be safe on the roads ! Seriously

''This thing of chasing our cars down the freeway, it's not safe , changing lanes in a crazy manner at 65mph is not on b (sic).''

Niall's desperate plea comes as thousands of Directioners across the globe await an announcement about former band member Zayn Malik, following a mysterious hashtag which trended worldwide earlier in the week.

On Friday (24.07.15) the hashtag #ZaynIsComingBackOnJuly26 began trending fuelled by excitable fans who suggested it may mean the 22-year-old singer - who spectacularly quit the band in March following four years in the group - would be returning to the band, although a representative has since insisted the claims are false.
