Businessman Jim Mansfield Junior has been found guilty at the Special Criminal Court of attempting to pervert the course of justice by directing that CCTV footage be destroyed.
However, he has been acquitted of conspiring with others to have one of his employees kidnapped by a criminal gang.
Mansfield, 54, and from Tasaggart House in Saggart in Dublin, had pleaded not guilty to both counts in a trial that started in late 2020.
He denied conspiring with one or more people between 1 January and 30 June 2015, to falsely imprison Martin Byrne who had previously been Head of Security at the CityWest Hotel when it was owned by the Mansfield family.
And he also denied directing Mr Byrne's brother, Patrick Byrne to destroy CCTV footage from the morning of 9 June 2015 at Finnstown House Hotel in Lucan.

The three judge court found there was insufficient evidence to find that Mansfield was party to a plot by former terrorist Dessie O'Hare and violent criminal Declan Duffy to kidnap Mr Byrne and remove him from his home at an apartment complex owned by Mansfield.
O'Hare was jailed for seven years in 2019 for falsely imprisoning Mr Byrne. Duffy was jailed for six years in 2018 for the same offence.
Giving the court's judgment, Mr Justice Alex Owens said although the "most likely" scenario was that Mansfield "lured" Mr Byrne to a meeting with O'Hare and Duffy on the morning of 9 June 2015, with a view to facilitating his kidnap and removal from his home, the court could not reasonably exclude the possibilities that O'Hare had misled Mansfield about the purpose of the meeting or that Mansfield was not privy to the kidnap plot.
The judge said there was no doubt that Mansfield had lied to gardaí when he claimed he had nothing to do with the meeting but he said that was not sufficient to prove that he was involved in the plot.
However, the court found Mansfield had directed Patrick Byrne to destroy a hard drive containing CCTV footage which showed Mansfield leaving the Finnstown House Hotel with Martin Byrne on the morning in question.
Mr Justice Owens said Mansfield had later described the men who attacked Martin Byrne as "these animals" and had arranged to destroy a piece of evidence which connected him to the men and to the events which had put Martin Byrne in harm's way.
Defence Counsel Bernard Condon applied for bail, saying he had been acquitted of the substantive issue before the court and had always answered his bail.
However the court remanded Mansfield in custody saying he had been convicted of quite a serious offence relating to quite serious matters.
The sentencing hearing will take place on 7 February.
Prosecuting counsel, Shane Costelloe said he needed time to gather victim impact statements although Mr Condon said he did not believe such statements applied in respect of the charge for which Mansfield has been convicted.
