"Joe seemed to have dropped his key to #JulianAssange's cell, I was merely returning it!," Mr O'Reilly wrote on Twitter.
"We need to #FreeAssangeNOW! O'Reilly was wrestled to the ground by members of the GardaiSiochana outside #Dublin Castle where a banquet was underway during the #Biden visit," the post read.
A video posted on Mr O'Reilly's Twitter account appeared to show him sitting on the ground as three Garda Siochana officers stood around him.
Mr Assange, an Australian activist and publisher who co-founded WikiLeaks, has been held in London's Belmarsh prison since 2019 and is .
He was taken to the maximum security prison after at the Ecuadorian embassy in London, which had sheltered Mr Assange for more than six years, following a decision by then-president Lenín Moreno to withdraw his asylum.
Prior to entering the embassy, Mr O'Reilly, a Londoner who is originally from Brisbane, was one of two volunteer bodyguards who would escort Mr Assange between court appearances.
The US has faced calls to drop its extradition proceedings against Mr Assange.
Earlier this week, 48 Australian MPs and senators signed a letter to US Attorney-General Merrick Garland urging him to end the pursuit of Mr Assange.
"A clear majority of Australians consider that this matter has gone on for far too long and must be brought to a close," said the letter, which coincided with the fourth anniversary of Mr Assange's imprisonment in the UK.
"We implore you to drop the extradition proceedings and allow Mr Assange to return home."
Appeals to stop his extradition are currently before the UK courts.
