The 31-year-old is wanted to stand trial for the offence of dangerous driving causing the deaths of friends Nathan Fullerton (17) and Nathan Farrell (18) on April 29, 2017.
The man, who is from Buncrana, was expected to appear before Carndonagh District Court today.
The incident happened when a car they were travelling in hit a wall before crashing into a tree on a straight stretch of the Quigley’s Point to Moville Road at around 3.35am on the morning in question.
The five, mostly teenage, friends were driving home from a night out at a local disco when the crash occurred.
The PSNI said the man is also wanted to stand trial for possession of a controlled drug for the purposes of sale and supply, in connection with an offence alleged to have taken place in the Donegal area in July 2020.
The man was arrested in the North of Ireland on September 15, 2022, and was extradited to the Republic of Ireland today.
Sergeant Davey, from the PSNI’s International Policing Unit, said, they continue to work closely with their partners to locate, arrest and extradite those wanted in other jurisdictions.
“Our message is clear that Northern Ireland is not a safe haven for anyone trying to avoid arrest or the consequences of their actions,” he said.
“We will relentlessly pursue anyone trying to delay or deny justice to victims of crime.”
