An investigation into the video's content was carried out by police
Two police officers who blasted out a rap song from their Essex patrol car late at night have been given "words of advice" by a senior officer.
A film was posted on YouTube showing the car in Chelmsford with KRS-One's Sound Of Da Police being played.
A spokeswoman said: "They acknowledged they had inappropriately used the patrol car PA system."
The YouTube clip shows the car blasting out the line "Woop, woop, it's the sound of da police".

Asked about the incident in April, when the footage came to light, Police and Crime Commissioner Nick Alston, said the question had "caught me on the hip hop".
"I like people to have a sense of humour," he told BBC Essex.
"It's a question for the Chief Constable, but if someone's sense of humour got ahead of their judgment then maybe it's forgivable, but let's have a look at the facts."
Sound of Da Police was released by US rapper KRS-One in 1993 and refers to police in New York.
