Police Arrests Mercedes Benz Driver

Resisting arrest in the UK is not illegal, but you can be prosecuted if you commit "assault with intent to resist arrest" which means being violent towards the police officer while being arrested. Also to be noted that it is illegal to resist or wilfully obstruct a police officer in the execution of their duty by interfering with someone else's arrest. As I arrive to the scene I noticed two police officers talking to a Mercedes Benz Driver, but things escalated very quickly. The Mercedes Benz driver seemed to be unhappy about the arrest as he did not do anything and he resisted the arrest. I just happened to be there as the scene unfolded, and said that I would upload the clip if it helps any of the parts.
The car details are written here with the sole purpose of the guy on the video to be able to search it.
This happened on the 2nd of March at around 5pm in front of Brockwell Park along Norwood road.

There are a number of offences which might apply if you are obstructive when a police officer arrests you. First, it is an offence to "resist or wilfully obstruct a constable in the execution of his duty". It is also an offence to assault a constable in the execution of his duty. You won't be found guilty of these offences, however, if the police officer is acting outside his powers; in that event he is not acting "in the execution of his duty". Secondly, there is a more serious offence of "assault with intent to resist arrest". Again, however, in order to be guilty of this offence it must be proved that the person attempting to carry out the arrest had the right to do so.

In order for an arrest to be lawful, the conditions set out in section 24 of the Police and Criminal Evidence Act 1984(PACE) must be met. Section 24 provides that a constable may arrest anyone who has committed an offence, is in the act of committing an offence or is about to commit an offence. He may also arrest anyone whom he has reasonable grounds for suspecting of these things. In order for this condition to be met the constable must honestly believe in the person's guilt, and that belief must be reasonable on the basis of the facts known to him. Evidence which shows that the arrested person did not in fact commit the offence may be relevant to the question of whether the constable had reasonable suspicion, but it will not be determinative.
