Egyptian judicial sources say a court has ordered the release of 10 members of the banned Muslim Brotherhood, including a senior member of the opposition group.
The source says the 10 men have not yet been released.
They were among at least 16 people detained in a police raid in August on the home of a Brotherhood member in Cairo. Those ordered released include Essam el-Erian, a member of the Muslim Brotherhood's political department.
The government has detained many Brotherhood members in recent months as part of a crackdown on the group.
The Muslim Brotherhood, an Islamist group, has been banned in Egypt for more than 50 years, but its members run for political office as independents.
The group controls about one-fifth of the 454 seats in Egypt's lower house of parliament.
The Muslim Brotherhood says it wants to transform Egypt into an Islamic state through democratic reforms.
