Raj was greeted by his supporters at his residence 'Krishna Kunj' at Dadar in Central Mumbai, where some
supporters brought the cake with Owaisi's image on it and cut it.
The action drew condemnation from AIMIM, whose MLA Waris Pathan demanded action against those who cut the cake.
Raj had targeted Owaisi triggered a row early this year saying he would not chant 'Bharat Mata ki Jai', even if a knife is put to his throat.
"Come to Maharashtra, I will put a knife to your throat," the MNS chief had said.
