This video was recently sent to me. I sent it to various media outlets and Merseyside Police (who had already seen it last year and took no action against the officer concerned). This is the response from Merseyside Police.
A Merseyside Police spokesperson, said: "During the evening of Monday, 23 July (2012), Merseyside Police was made aware of a video on YouTube that appears to show a police officer behaving in an inappropriate manner.
"The footage was obtained and an immediate investigation was launched by the Force’s Professional Standards Department. “A 31-year-old serving police officer has been placed on restrictive duties whilst the investigation into the matter is conducted.
