Ibrahim Mattar also said the main Shi`ite Wefaq bloc would quit parliament.
"All the members are going to resign. The decision is taken," he told Reuters.
Asked why the bloc, which holds 17 of the assembly`s 40 seats, had decided to resign, he said it was because of the overnight raid.
"We feel there was a decision to hurt people."
Mattar said the whereabouts of about 60 people remained unclear, hours after police forced demonstrators to abandon Pearl square, an intersection in Manama which they had hoped to turn into a protest base similar to Cairo`s Tahrir square.
"Are they in prison or did they escape and are now hiding in houses? We don`t know," he said, adding that his figure was based on telephone calls received from worried relatives.(*)
