Walmart said Tuesday that it would stop selling “Bulletproof: Black Lives Matter” T-shirts on its website after a request from the head of the national Fraternal Order of Police.

The Washington Post reported that T-shirts that read Black Lives Matter, Blue Lives Matter and All Lives Matter are also on the website.

Chuck Canterbury, the president of the FOP, sent a letter Tuesday to the CEO of Walmart, Douglas McMillon about the shirts he called “offensive.”

“I urge you to prohibit the use of the use of the Walmart name and website for the retail sale of these products,” the letter read.

Time reported that the shirts were sold through Walmart’s website by Old Glory Merchandise.

“Like other online retailers, we have a marketplace with millions of items offered by third parties that includes Blue Lives Matter, Black Lives Matter and All Lives Matter merchandise. After hearing concerns from customers, we are removing the specific item with the ‘bulletproof’ reference,” Walmart said in a statement.
