The arrest warrants were issued in a case registered against the leaders for facilitating MQM chief Altaf Hussain's July 12 speech critical of the military establishment.
The court acted on different FIRs registered by private complainants who alleged that the MQM leaders had attended a public gathering and listened to Hussain's outburst against the security agencies in his speech.
In his speech, Hussain had accused the paramilitary forces of torturing and killing his party workers.
According to details, the MQM leaders were charged under Section 12 (collection of evidence in the absence of accused) of the Criminal Procedure Code (CrPC).
Akhtar was nominated for the important Mayors post just last week after the party's landslide victory in the local bodies elections in Karachi and Hyderabad.
The judge also issued directives to the police to arrest and present the accused before the court on January 2.
