One Direction star Louis Tomlinson has been arrested for allegedly attacking a photographer at an airport while collecting his luggage.

The 25-year-old star had been returning from a week in Las Vegas with his partner, fashion blogger Eleanor Calder, when photographers spotted the pair.

The incident, which happened in Los Angeles on Friday night, saw him attend a police station on Saturday morning.

It is alleged the photographer had been taking pictures of the pair when the star is accused of knocking him to the floor, leading to the man sustaining injuries to his back and head.
