'No Catcalling' signs will come down New York City

NEW YORK CITY -- There's a new campaign to end the harassment of women and the signs of it are everywhere, but they will soon be coming down.

The signs popping up in the New York City say things like "No catcalling anytime" and "No catcalling zone."

They're being put up by the non-profit clothing company Feminist Apparel and a feminist group based in Philadelphia, but DOT says the signs can't stay.

"While we understand the concept of this campaign, these signs were placed without permission. DOT has not received any formal complaint about them but we are proceeding with their removal as we are made aware of the location (s) and/or come across them," a spokesperson said.

The non-profit "Hollaback!" says the signs carry an important message.

"Street harassment is something that has been normalized over time, and when we talk about street harassment we're talking about verbal harassment and catcalling, but also non-verbal gestures. The signs are a very interesting way to approach the subject, public art is really important in raising awareness," said Debjani Roy, the deputy director of Hollaback!

More than 50 signs had gone up and they planned to have them in every borough by the end of the week.
