A lawyer for a prominent Bahraini opposition leader arrested weeks after being freed from prison says his client will appear in court on new charges later this month.

Ibrahim Sharif was freed in June after serving more than four years behind bars for his role in 2011 protests calling for political reform, then detained again last month over comments that authorities allege incited hatred and encouraged the overthrow of the government.

He is the former secretary-general of the secular, leftist National Democratic Action Society, which also goes by the name Waad.

The official Bahrain News Agency reported that the trial of an unnamed "regime-change instigator" will begin at the Higher Criminal Court on August 24. Defense lawyer Sami Siyadi confirmed Wednesday that Sharif would face trial on that date.
