Ms Passaris had gone to court to hear Mr Owino's bail ruling when a group of rowdy youth started hurling insults at her.
The youth called her a traitor for sending an apology to the Kenyatta family in a Facebook post following Owino's recent demeaning comments.
The suspected goons asked the Woman Rep to apologise and pull down the Facebook post.
It took the intervention of Lawyer Otiende Amollo who was part of the team representing Owino to calm the rowdy group down.
On Monday, Passaris condemned Owino over his derogatory remarks believed to have been directed at President Uhuru Kenyatta.
She stated that the former student leader had crossed the line and urged leaders to avoid abusing their freedom of expression and instead exercise responsibility in what they say.
Over the weekend, Babu was accused of referring to President Kenyatta as a puppy.
Owino spent Monday night at Pangani Police Station and Tuesday night at Kileleshwa Police Station.
He appeared before Magistrate <strong>Francis Andayi</strong> and was charged with two counts, one of subversion and another of uttering abusive words against the President, to which he pleaded not guilty.
