Seven 10-inch swastikas were found drawn in purple marker on the pillars, brickwork and stone at a pavilion in Theodore Roosevelt Memorial Park, police say.

Police say the offensive drawings were put there either Wednesday or Thursday.

State Assemblyman Charles Lavine says the hateful images don't just offend him as a state lawmaker. He says he's also personally offended.

"Anyone who does this in the cover of night in the cover of darkness, which is what they did, does not want to be seen," says Lavine. "They don't want anyone knowing who they were."

Lavine says his grandmother came to America from Russia when Teddy Roosevelt was president. Lavine says the symbols are anti-American and he hopes that anyone who sees them or hears about them speaks out against them.

In a statement to News 12, Oyster Bay Town Supervisor Joseph Saladino said, "Hatred, bias, or intolerance of any kind have no place in our town."

Saladino says public safety officers are checking security camera footage from the park.

Nassau County police are asking anyone with information to come forward or call Crime Stoppers at 1-800-244-TIPS.
