I was scene guard at an incident recently on a Saturday night. A member of the public decided to deliberately duck under and cross our tape barrier as a lark with his mates. Afterwards, I’ve been trying to think of the best legislation I could have used, had I chosen to arrest rather than just have strong words of advice. Section 19 PACE and then Section 117 gives me power to enforce the cordon, which I used. I could have used Section 5 POA but in this case, I don’t think it would have been appropriate as there was nothing obusive or offensive. It might for other situations. D&D might also be used on other occasions in a similar vein. Possibly Perverting the course of Justice by deliberately contaminating a crime scene. or Obstructing a police office in the execution of his duties. any thoughts or examples other officers have made use of?
