An anti-terrorism court on Saturday indicted Mayor Karachi Waseem Akhtar along with 20 other accused in the May 12 carnage case.
The court indicted the accused after they pleaded not guilty and summoned them on October 27.
Four cases had been registered at the airport police station against the accused, of which an indictment was issued for case number 86/2007.
The court had also declared nine suspects as absconders in the case.
Earlier in September, the Sindh High Court (SHC) ordered the formation of a Joint Investigation Team (JIT) to probe the May 12 carnage in the port city which left several dead in 2007.
A two-member bench comprising Justice Iqbal Kalhoro and Justice K.K Agha had also directed the formation of a judicial tribunal to scrutinise the case.
Chaos erupted on May 12, 2007, upon former chief justice of Pakistan Iftikhar Chaudhry’s arrival in Karachi. He was scheduled to attend an SHC bar ceremony but was stopped at the airport.
In the riots that followed, more than 50 people were killed and over 100 injured when rallies of various political parties and lawyers were attacked.
Former president Pervez Musharraf, founder of MQM, former advisor to the interior ministry and Akhtar were named in the petition which alleged that MQM caused the bloodshed in Karachi at the behest of former president Musharraf.
