Lakeville (WBZ Newsroom) -- The Secret Service and Lakeville Police are investigating an act of vandalism at a country club.
Lakeville County Club workers discovered a message on the 18th green Monday that included a swastika and the President's name carved into the turf.
The golf course's owner says the vandals snuck in at night.
Course owner Gary Mosca tells WBZ-TV, "it's just so insulting to the human race and it just shouldn't be part of our doings by anybody. I just can't understand it. It's unforgivable."
Mosca says he's going to have to call in turf experts to repair the damage.
He doesn't expect it to be completely fixed until next spring.
