In view of the aforementioned statement, mm, might i point you in the direction of:
• Assault on a police constable in execution of his duty – Section 89 Police Act 1996;
This offence occurs when an offender assaults either a police officer acting in the execution of his or her public duty or someone helping them in this duty. The assault does not result in any serious physical harm and includes acts like pushing and shoving. The injuries sustained are equivalent to those for common assault - if more serious injuries were inflicted, then a more serious charge, like ABH, would be brought. The new guideline gives a sentencing range of a fine up to 26 weeks imprisonment for this offence. The maximum penalty for this offence is six months imprisonment.
As this would include the above as far as I could throw one !, ;)
