AAP activists present there immediately pulled Vaghrekar, out of the conference hall.
Kejriwal, without naming any party, said "it was done by those whose vested interests were being hit due to AAP's growing popularity."
AAP leader Kumar Vishwas termed it as an act by BJP out of "frustration" while BJP said it was "low-grade" politics.
"This is an act of BJP which is frustrated with AAP's growing popularity in Delhi. It is sending such type of people to disrupt our programmes," he said.
