Brad Pitt is being investigated by the FBI and social services in Los Angeles amid reports he got 'verbally abusive and physical with his children' on a private jet.

The family is said to have been on a flight home from France when he allegedly became 'wasted' and started 'screaming' before continuing the 'rant' on the tarmac when the plane landed, trying to leave the scene in a fuel truck.

TMZ reports that the alleged episode, last Wednesday, prompted Angelina Jolie to split from the 52-year-old the next day and then file for divorce.

A source close to Pitt said: 'He takes the matter very seriously and says he did not commit any abuse of his children.

'It's unfortunate that people involved are continuing to present him in the worst possible light.'

On Thursday morning, a police car was seen arriving at the Jolie-Pitt compound in the Hollywood Hills, were Pitt is believed to be staying while Jolie and the children are at a Malibu rental home.

The FBI is investigating the incident because it happened on a flight, and US Weekly is reporting that the anonymous call came from someone on the plane as it headed towards Los Angeles, which led to members of DCFS meeting the family on the tarmac and questioning them on the scene.

TMZ reports: 'The plane landed a week ago Wednesday just before 8 PM at an airport in Minnesota. That's when eyewitnesses say Brad was "out of control" on the tarmac and even tried to leave in a fuel truck.

'Our LAPD sources say because the incident occurred in the air, the FBI has jurisdiction. The ACU then closed its file and referred the matter to the FBI.'

The LA County Department of Children and Family Services meanwhile told KTLA reporter and anchor Wendy Burch there is an investigation into child abuse claims.

However a spokesman told DailyMail.com they have strict laws that don't allow them to confirm or deny the subjects of investigations.

A colleague of the couple meanwhile tells Access Hollywood that while Jolie wants the children to have a relationship with Pitt, there are no plans for visitation between the six kids and their father at this time.

And while the divorce did not come as a surprise to Pitt, he was thrown off by the time according to those close to the actor.

'He was appealing to her to do this quietly – not to save the marriage but to consider the well-being of the children – and it was ignored,' a source close to the actor told People.

The source added: 'There was clearly a breaking point, where she'd just had enough. He may have been broken himself and said he couldn't go on, and she reacted. This has been difficult for a while.'

A source close to Jolie meanwhile said: 'Things built and built over time – it wasn't any one thing.

'She's loved this man for several years, and [divorce] is not something you do impulsively.'

That source said that in the end Jolie did 'what she needed to do.'

The Jolie source added however: 'They have six kids together and are always going to be in each other's lives.'

Jolie did not respond to a request for comment while a spokesperson for Pitt reiterated the actor's statement from earlier in the week in which he said: 'I am very saddened by this, but what matters most now is the well being of our kids. I kindly ask the press to give them the space they deserve during this challenging time.'

The Hollywood star, 52, is said to have 'offered to improve to make himself a better person' in a bid to avoid divorce

The actress addressed reports she and Mr Pitt had sparked a romance during the filming of their new WWII drama Allied

Both sides have been adimant that there was no extramarital affair and that both are committed to their children, despite false reports that Pitt had engaged in a relationship with his Allied costar Marion Cotillard.

On Wednesday, Cotillard revealed that she is pregnant with her second child and vehemently denied having an affair with Pitt.

Cotillard, 40, wrote a lengthy Instagram message to make the announcement and to dispel rumors on Wednesday before confirming that her partner of eight years Guillaume Canet is the father of her unborn child.

'This is going to be my first and only reaction to the whirlwind news that broke 24 hours ago and that I was swept up into,' the actress said in her post.

'I am not used to commenting on things like this nor taking them seriously,' she continued, 'but as this situation is spiraling and affecting people I love, I have to speak up.'

She concluded her message by wishing Brad and Angelina Jolie well.

'Finally, I do very much wish that Angelina and Brad, both whom I deeply respect, will find peace in this very tumultuous moment. With all my love, Marion.'

Her well wishes come despite a source telling DailyMail.com that Jolie was so jealous of Cotillard on the Allied set that she would not even speak to the French star.

Angelina completely ignored Marion on the set, and when Marion tried to talk to her she just looked the other way,' said the source, who is close to both Jolie and Pitt.

'Marion was devastated, here she is thinking she is going to meet this great UN ambassador and instead Angelina refuses to speak to the woman because of her own jealousy.'

Stress: Pitt reportedly became annoyed after his wife appointed William Hague's former colleagues Arminka Helic and Chloe Dalton to assist her with her political career (pictured)

Jolie filed for divorce from Pitt on Monday for 'the health of her family', two years after they wed at their French estate Chateau Miraval.

The actress filed papers citing irreconcilable differences as the reason for the split and asked for physical custody of the couple's three biological children as well as their three adopted children - Maddox, 15, Pax, 12, and Zahara, 11.

Pitt is said to have been furious over Jolie's appointment of Arminka Helic, 48, and Chloe Dalton, 37, two former political aides to British politician William Hague. A source told the Sun they were brought in to help with her campaign work and speech writing and urged Pitt to reduce the couple's support staff.

'Brad sees the women as a coven. He was furious at some of Arminka's decisions,' the source said.

The decisions are said to have included ditching Pitt's security team - some of whom had worked for the star for 20 years.

Lady Helic is seen as a key person on 'Team Angie' as the actress braces herself for the aftermath of her decision to divorce Pitt.

A source told Daily Mail's Alison Boshoff that Lady Helic is 'smart, strong, and impeccably loyal', adding that she is Angelina's 'assistant, adviser and best friend'.

Angelina watched Lady Helic be admitted to the House of Lords in 2014. They often travel together; recent trips include a visit to the International Criminal Court in the Netherlands and one to Burma at election time last summer.
