Dubai (UAE): A woman, detained for defying the ultraconservative Saudi Arabia's ban on female drivers, has been released by authorities, says a rights activist here.

Waleed Aboul Khair said that the 32-year-old woman, Manal al-Sherif was freed on Monday on an order from Saudi officials.

Al-Sherif had been detained since May 21 after posting an Internet video of her driving as part of a campaign for a
mass protest next month against the restriction.

Al-Sherif had been ordered to remain in custody until at least early June.

The reason for the early release was not announced by authorities but it followed growing pressure from rights
groups and others in Saudi Arabia and the West.
