Police are investigating after a string of businesses in Brooklyn and Manhattan received hate mail that features a swastika.

At least seven businesses got anonymous fliers like this one between last Friday and Monday, which say "Make America Great Again."

Weiss Kosher Bakery in Borough Park was one of the shops to get the hate mail, which police said is filled with racist, homophobic, and anti-Semitic language.

"I wasn't scared, but I was shocked and disgusted," said bakery owner Abraham Weiss. "It's ridiculous that in 2017 there's such a hatred — there's no reason for that.

"It's worthless to talk about it," one man said. "It's very painful to talk about, and I hope the people that did this will never do this again."

Other places targeted were the Harlem Business Alliance, a Starbucks on West 145th St., a jewelry store on East 116th St, and the Israeli Mission.
