A man was being held by French police Tuesday over an attack last month on a woman in the center of Paris that was captured on video.
Marie Laguerre was punched in the face on July 24 in Paris' 19th arrondissement after challenging a man who she says was sexually harassing her.
The video, which she then shared on her Facebook page, sparked outrage across the world and led to a new discussion about the harassment faced by women on an everyday basis.
The man suspected of punching Laguerre was arrested on Monday and was still in custody on Tuesday, according to a spokesman for Paris prosecutors, reports CNN.
Laguerre has been asked to identify him on Wednesday, adds the BBC.

The encounter, captured on video, lasts just seconds. After hitting her in the face, the assailant turns to walk away as witnesses at a nearby café stand up to confront him.
