Mr Wanjigi was roughed up by police on Wednesday.
Earlier on Thursday, security had been heightened at Nyeri law courts in anticipation of the appearance of the businessman.
Meanwhile, his lawyer Kiogora Mugambi on Thursday March 1, said Mr Wanjigi won’t appear in court until he is informed of the charges against him.
On Wednesday, drama unfolded along Museum Hill Road in Nairobi on as plainclothes police officers intercepted a vehicle belonging to businessman.
Mr Wanjigi is said to have refused to roll down his vehicle’s window and instead took a video of the rifle-wielding officers.
The officers, believed to be from a special police unit, are seen in the video demanding that Mr Wanjigi opens the window so that he can be served with a notice to appear in a Nyeri court Thursday morning to answer to criminal charges.
But, after noticing that the commotion was causing a scene, they pinned the notice on the windscreen of Mr Wanjigi’s vehicle.
The notice states that Mr Wanjigi appears before the Nyeri Magistrate’s court at 8 am on Thursday (today) to answer to an unspecified criminal charge, which was only described as “251 of 2018”.
“You are hereby commanded to attend this court at 8 am on March 1, 2018 and not depart without leave of the court or until the case is finished,” the notice read.
After the officers left, Mr Wanjigi told journalists and onlookers that the government is out to frustrate him because of his political stand.
“It is going to be over soon. Kenyans, I am telling you, a dawn is coming. These dark days are going to be behind us soon,” Mr Wanjigi said.
“The other day it was my passport, the time before that was gun revocation, and as I said before, this is becoming comical, another day it was an obituary. It is a persecution.
I would like to address my old friend, he was my friend until he burst the door of my house, President Uhuru Kenyatta you will not be legitimate by persecuting Kenyans… You will not become legitimate by persecuting me,” said an agitated Wanjigi.
Mr Wanjigi has, however, been charged in absentia for importing illegal guns into the country. He will take plea on Monday.
"They will be no need to serve him afresh. The summons are genuine and worth issued, signed and stamped. He should appear here on Monday," the judge said.
