On Thursday, prominent human rights blogger Zainab al-Khawaja was roughed up, handcuffed and dragged off into custody from the same roundabout for refusing to end a sit-in. Protesters had massed along the highway after the funeral of a protester who opposition supporters say died during a rally. Witnesses say the man was hit by a police car.
Ali Salman, the leader of Bahrain's main Shia opposition group al-Wefaq, has called on the Gulf kingdom's authorities to release al-Khawaja.
"After the report, they return to the same methods... they kill more people they put more people in prison," said Salman.
"It sends a bad message from the regime that it does not respect the recommendations of the report."
Salman also said he is to hold talks with the British minister for the Middle East, Alistair Burt, on Monday in London.
