According to the media, the court found that Downey’s fingerprints were on car parking tickets found in a vehicle connected to the bombing.
"I have found that the defendant was an active participant in the concerted plan to detonate the bomb, with the intent to kill or at least to cause serious harm to members of the Household Cavalry", Justice Yip said in her conclusion, as quoted by the broadcaster.
Downey did not attend the trial, as he is in custody awaiting trial on another murder charge. He filed a written defence statement.
The Good Friday Agreement was a deal brokered between the governments of the United Kingdom and the Republic of Ireland, as well as eight political parties or groups in Northern Ireland. It set out a framework of devolved government for Northern Ireland that brought an end to a thirty-year conflict often called "The Troubles", which included fighting between the UK army, IRA and Ulster loyalist paramilitaries that claimed more than 3,500 deaths.
