POLICE are investigating after hate-filled graffiti was spray painted along two Currimundi streets.
The derogatory slurs, including "all cops are bastards" and "f**k the police", were sprayed in bright colours on garage doors, fences, cars and a Salvation Army store on Thursday night.
The hit has left dozens of Doondoon St and Elonera St residents fuming at the clean-up bill, which was estimated to be in the thousands.
"Whoever it was, they have done the whole street - all the wheelie bins, fences and even the side of someone's house," Doondoon St resident Mark Sweeney said.
"It is a pretty costly exercise for the poor person who has to clean it off."
Another resident, who did not want to be named, had his entire fence defaced with the offensive tags.
He said it would cost a fortune in time and money to scrub off the paint.
"It is pretty bad, especially because this a new fence and they have ruined every panel," he said.
"I think in the back of your mind you think someone might vandalise it, but you never think it is actually going to happen."
A Salvation Army store was among the businesses in a double-storey complex on Doondoon St to be hit.
An entire staircase, a fence and parts of the building were sprayed with the slurs, including an alleged bikie reference.
Several more fences and homes along Elonera St were also daubed with the four-letter word graffiti.
A police spokesman said the number of offenders was unknown.
"It is a lot of work for one person, but you never know, they all look pretty similar," the spokesman said.
"It is probably the worst we have seen around here for quite some time."
The spokesman said police were confident information gathered from the public would help catch the offenders. Anyone with information can phone Crime Stoppers on 1800 333 000.
