The One Direction singer was arrested last week for allegedly attacking paparazzo Karl Larsen - who claims he was knocked unconscious in the row - before becoming involved in a brawl between his girlfriend Eleanor Calder and onlooker Ana Berra Herrera and a police report observed "fresh abrasions" on both his hands.

An arrest report obtained by DailyMail.com stated: "Susp Tomlinson grabbed vict. Larsen's leg and caused him to fall backward, then struck vict. Becerra in the eye. (sic)

LAPD Officer Tran wrote: "I asked Susp. Tomlinson if he recalled ever making any physical contact with Becerra Herrera. Tomlinson stated that he placed his hands on Becerra Herrera and in a pushing motion, pushed Becerra Herrera off of Calder and grabbed Calder to pull her away from Becerra Herrera.

"Officer Chen asked Tomlinson if he recalled sweeping Larsen's legs causing him to fall to the ground.

"Tomlinson said: 'I may have taken him down, I'm not sure, but I remember we both fell to the floor.

"While interviewing Tomlinson, we observed fresh abrasions on Tomlinson's both hand knuckles."

Meanwhile, according to the report, Eleanor admitted she may have "forcibly" taken Ana's phone in a bid to stop her taking pictures of them.

The report said: "Calder stated that she tried to slap the phone out of Becerra Herrera's hands and may have forcibly remove the cellphone from Becerra Herrera's hands.

"Calder stated that Becerra Herrera started to hit her with closed fists and kicked her. Then they all got into a physical fight with each other. Calder said this was when Tomlinson pulled her away from Becerra Herrera."

Meanwhile, Ana accused the 'Just Hold On' singer of punching her in the eye and breaking her glasses, while her wife Bianca Garza said the 25-year-old star grabbed her partner by the waist "in a bear hug style" and threw her over his shoulder.

Three witnesses to the row gave statements, with American Airlines worker Dominique Robinson siding with Louis and Eleanor.

She explained she had warned the photographer away from the couple after they had asked for her help and described how Eleanor was "pinned to the wall" in a foetal position as she tried to avoid being kicked and punched.

The report said: "Robinson said all of a sudden both Tomlinson and Larsen fell to the floor. Robinson said she heard more noise coming from Calder's direction and saw that she was pinned to the wall of the seating area covering herself in a protective manner, fetus position, while Becerra Herrera was striking Calder with closed fists and her feet."

However, another witness, Aguirre Poblando told police she saw Louis "use his hand" to grab Karl by the leg, and observed Eleanor "suddenly start to attack" Ana, a version of events backed up by Starbucks worker Arlett Lyons.

Louis is due to appear in court on March 29 and could face up to six months in jail.
