WA Police will be seeking to extradite a Perth man who was arrested in Europe along with dozens of other suspected mobsters in mass raids targeting a powerful branch of the Italian mafia.

Commissioner Chris Dawson said he was pleased Domenico Condo, who has an outstanding arrest warrant in WA, had been apprehended.

“We’ve been actively pursuing him. We will be seeking him to be extradited to face justice in Western Australia when that’s available,” Mr Dawson told reporters on Thursday.
