MOUNTAIN BROOK, Alabama -- Mountain Brook residents awoke to a vulgar sight near the post office on Montclair Road on Sunday, June 30: graffiti spray painted on the wall of a foreclosed property portrayed a hate-filled message targeted toward the police.

By Monday morning, city crews worked to cover at least part of the message and placed a tarp over the offensive language.

Mountain Brook City Manager Sam Gaston told AL.com today that police are investigating the incident.

"Public Works will try to remove the word, but if they can't," said Gaston in an emailed statement, "we will paint over it."

Ronnie Vaughn, public works director for the city, confirmed today that the offensive word has already been removed from the wall using a "graffiti remover and a pressure washer."

Unfortunately, the pressure washer went down this afternoon with mechanical problems before crews could finish the job, but Vaughn said his team will continue to try and remove more of the graffiti in the morning.
