LaSalle police are investigating another incident of disturbing graffiti.
It was discovered July 30th at Brunet Park.
Police say it had a "similar message" to the graffiti found at Petite Cote Conservation Area last month which referenced the shooting of five police officers in Dallas and other incidents where police officers had been killed.
Another incident of disturbing graffiti was found in May.
Police are asking for witnesses to come forward.
