The 22-year-old social media personality was said to have been extracted from the Australian jungle by his "representatives" due to "circumstances outside camp".
But it is now being reported that Maynard - who is the younger brother of pop singer Conor - will also be quizzed over allegations about sending inappropriate messages to a female fan, The Mirror reports.
In the tweets, which were posted between 2011 and 2013, the vlogger repeatedly used the n-word, insulted disabled people and referred to other users as "f******".
A statement from his spokesperson said: "In the last few days Jack has been the subject of a succession of media stories which he has been unable to respond to".

Get Me Out Of Here! due to circumstances outside the camp.
I'm a Celebrity. Get Me Out of Here! continues on TV3 tonight from 9pm.
"Since it is only fair that everyone should be aware of any allegations made against them and should also have the right to defend themselves, it was agreed it would be better to bring him out".
His rep later confirmed that the YouTube sensation was leaving the ITV show so that he could respond to the allegations made against him.
"He would never use that language now and realises this kind of retaliatory, inflammatory, insulting language is completely unacceptable".
Jack appeared on Tuesday's show, but presenters Ant and Dec revealed he had left the jungle, telling viewers they couldn't vote for him in Wednesday's Bushtucker Trial.
Jack, who has 1.2m YouTube subscribers and thousands of followers on his Twitter and Snapchat accounts, has yet to share an update regarding his sudden jungle departure.
