Vandals armed with spray paint cans reportedly struck Sunday in the Valparaiso area and in Michigan City.
The playground equipment near the Shorewood Forest clubhouse was spray painted with various colors, and a racist term was spray painted on an electrical box, according to Porter County police.
Several stop signs throughout the subdivision were also painted, police said.
A video surveillance camera showed a white or silver two-door Jeep Wrangler in the area at the time of the damage, which was shortly after midnight on Sunday.
Michigan City police reported that someone spray painted vehicles, garages and fences early Sunday within neighborhoods at the center of the city.
Police said there were 20 incidents of swastikas, gang rhetoric and profanities painted.
Police said the vandalism did not appear to be targeting anyone specifically.
