Addressing a press conference here, Khan asserted that there's massive corruption happening in the city and claimed that Karachi had been "abandoned" by political parties.
"Karachi is seen as a cash cow by the people in power," he said.
"Mafias prevail in this city. The tanker mafia for example - citizens do not have access to water because of it... The Rangers have been posted in the city because [political parties have] ruined the police," he added.
Last week, Khan skipped voting in the Senate (Upper House of Pakistan Parliament) election. (ANI)
