Ibori, who was the governor of Delta state between 1999 and 2007, was released from a United Kingdom prison recently.
Uduaghan, who stated this in a Facebook post on Tuesday, asked those involved to “stop it”.
Ibori, who was the governor of the oil-rich state between 1999 and 2007, was released from a United Kingdom prison on Wednesday after serving a concurrent13-year jail term for money laundering.
The Southwark Crown Court jailed him on April 17, 2012 after he pleaded guilty to a 10-count charge of money laundering and conspiracy to defraud.
Since his release, friends, family member and political associates have been paying him visits in his London home, where he is under house arrest pending the conclusion of his asset confiscation case.
A video of one of such visits which has been trending on social media shows a Senator from the state, Peter Nwaoboshi, boasting about how Ibori “installed” governors and lawmakers from prison.
The video immediately drew public criticisms with many already calling for Ibori’s extradition and further prosecution in Nigeria.
Uduaghan wrote: “For those going to London to see Chief James Ibori and posting pictures and making comments, please stop it.
“We appreciate your love for him but you can go quietly without the unnecessary publicity.
“You are creating more problems for him than you can ever imagine.
“Nigeria is a complex country and you must understand and respect people’s sensibilities.”
The News Agency of Nigeria (NAN) reports that Uduaghan, who is Ibori’s first cousin, is largely blamed by many for the latter’s travails.
