Louis Tomlinson has been released on $20,000 bail after being arrested at LAX on Friday (03.03.17).

The 25-year-old One Direction singer was taken into police custody following an altercation with a paparazzo at baggage claim, after he and his girlfriend Eleanor Calder flew in to Los Angeles International Airport from Las Vegas.

A source told TMZ that the paparazzo ''was too close for Louis' comfort, so he allegedly pulled the photographer to the floor by his legs. The photographer fell backwards and struck his back and head on the floor.''

Louis' girlfriend also reportedly got into a physical altercation at the airport, with a woman who started recording her as she tried to leave.

And a source told The Sun: ''Louis was really upset. After being filmed he told the snapper to stop, but he didn't take kindly to the request.

''The row turned into a scuffle causing airport security to pull them apart.''

Louis' lawyer Martin Singer said: ''The paparazzi provoked and caused the altercation that occurred with Louis. It's not the first time that a paparazzi has created an altercation with a celebrity. While the altercation was going on with the paparazzi, three other individuals were attacking his girlfriend during this incident and he came to her defence.''

Louis - who was taken into custody following a citizen's arrest - was released less than an hour after he was booked for simple battery but he is due to appear in court in Los Angeles on March 29.

The star - who has 14-month old son Freddie Reign with Briana Jungwirth - split from fashion blogger Eleanor in 2015 after three years together but they recently reconnected, following his break-up with actress Danielle Campbell.
