UP Police have registered a case against YouTuber Prakash Kumar, commonly known as 'Puneet Superstar', for referring to Bahujan Samaj Party (BSP) president Mayawati as "Mummy" in a video. Police took action after BSP leader Narendra Mohit lodged an FIR against him on Wednesday. Puneet later issued an apology, saying he had no intention of offending anyone.
