Iranian opposition supporters have launched an online campaign to free a student activist accused of dressing as a woman to try to avoid arrest.
Hundreds of men have posted photos of themselves wearing Islamic headscarves as part of the "Be a man" campaign to show solidarity with Majid Tavakoli.
He was arrested during protests in Tehran on Monday and state media showed images of him in headscarf and robes.
