"Shame! Instead of appreciating Aamir, the great grandson (great grand nephew) of Maulana Azad for highlighting the real issues, some sick people are abusing him," Akhtar posted on his Twitter page Monday.
Aamir made his TV debut with "Satyamev Jayate" (SMJ) in May 2012 and the show, dealing with sensitive social issues like female foeticide, domestic violence and child abuse, received a warm welcome from TV viewers after it went on air on Star Plus.
Some of the episodes dealing with female foeticide and malpractices in the medical field recorded the highest ratings.
The show's second season went on air on STAR India channels March 2. Its first episode dealt with the issue of rape, and the second episode, beamed Sunday, talked about police force.
A defamatory campaign against Aamir began on a social networking site, alleging that when at the end of the show, Aamir asks for donations for Humanity Trust, the money is used for masjid construction assistance and placement assistance for Muslim youth.
In reaction to it, Aamir registered a complaint with the Mumbai police and clarified that the "malicious messages are wrong and baseless".
