Dunedin police radios have picked up a strange interference in the past few days - the 1988 N.W.A rap song 'F**k Tha Police'.
Multiple versions of the track have been played, including Rage Against The Machine's 1998 cover, broadcast on Friday, January 5.
The lyrics of the classic song are critical of police, discussing police brutality and racial profiling.
The songs were repeated several times over the weekend, and again on Monday afternoon.
Otago coastal acting area commander Inspector Kelvin Lloyd told the Otago Daily Times police were aware that the transmissions were not coming from other officers.
"Any interference with a police radio constitutes a risk to public safety, and anyone caught doing this can face a penalty of criminal nuisance and up to one year imprisonment.''
In August 2017, pig grunts were broadcast over police radios in the lower North Island.
