Video shows Jade Jagger's boyfriend being pinned to the ground before couple ... trends now

Shocking video shows how Jade Jagger's new boyfriend was pinned to the ground by police before officers arrested the couple in Ibiza.

Witnesses told MailOnline how Anthony Hinkson who has been dating the daughter of Rolling Stones rocker Sir Mick Jagger for several weeks was behaving 'erratically' before his arrest.

At one point he is said to have gone into an up-market clothes shop and bought a designer dress for more than 2,000 euros as an impromptu gift for a waitress in a nearby restaurant.

Hinkson, 31, is also believed to have berated passers-by before police were called by concerned staff at the La Oliva restaurant where the waitress works.

He was seen being forced to the ground after allegedly assaulting an officer before being taken away in handcuffs at around 9pm on Wednesday.

Jewellery designer Jade, 51, who was inside the restaurant is said to have angrily complained to officers about her boyfriend's arrest.

Jade, who split two years ago from her ex-husband, allegedly accused police of being racist and is said to have pushed one officer before being arrested herself.

The couple were held overnight in police cells on the Spanish holiday island on suspicion of assaulting police and resisting arrest.

They are now due to appear in court in Ibiza Town, either later today at a special hearing or tomorrow morning.

MailOnline was told that the bust-up happened after Jade and her boyfriend went to the La Oliva restaurant in the heart of the old town area near Ibiza Castle.

A witness said: 'Jade's boyfriend was behaving very oddly.  I don't know what made him be like that.

'At one stage he came outside and went into Annie's clothes shop on the other side of the road where he bought a dress.

'He was bothering girls who were in the shop and making comments to a girl who was working there. He was not really making much sense. He was saying, 'Give me the f***ing dress. He was really rude.

'Then he took the dress back to the restaurant and tried to give it to the waitress. His behaviour was so erratic that the restaurant manager decided to call police.

'Seven police officers came and it looked like they tried to calm him down, but he was resisting them and saying really horrible stuff.

'He did not have his T shirt on and he was bare chested. The police managed to pull him down and they put handcuffs on him, but he was still resisting.

'I recognised Jade and she looked really upset about what is happening. She was demanding that police officers identify themselves, saying: 'I don't want to mess with anyone. Give me your names.'

'The cops kept telling her to stay out of it, but she was saying, 'You are just arresting him because he is black'. The police were telling her to stay at home, but she said, 'No, I am coming with you.'

'An officer told her, 'If you keep going, I will arrest you'. Then she was arrested as well.

I didn't actually see her pushing or anything like that.

'But I saw an ambulance arrive, and there were loads of police.'

The witness said that Hinkson left the restaurant about half an hour before his arrest and splashed out on a sleeveless gold dress by New York designer LaQuan Smith , priced at 2,102 euros on the shop's website.

They added: 'He was buying the dress for a waitress. He was saying, 'Try something on. I will buy it for you.' He was bothering everyone and screaming.

'It was just really weird
