The women were all arrested on the L train platform on March 28, for selling the sugary treats to passersby without a proper license to sell food, police said.
"They [make these arrests] all the time," a police source said. "It's going to happen more as summer comes around."
An officer spotted the first woman selling a churro to one commuter in exchange for $2 at about 5:15 p.m. and arrested her, police said.
The second woman was also arrested at the same time, and the third was collared for the same violation at about 11:55 p.m.
All three women were given desk appearance tickets, and are due in court on May 14, sources said.
