I am advised by the Garda authorities that the number of persons whose extradition has been sought by the Irish authorities in the period since 1 January, 1981 is 375. In the same period, 301 persons have been extradited to this country but that figure would include a small number of persons in whose case the request would have predated 1 January, 1981.
The other information sought in the question is not readily available from Garda records and it would not be possible to compile it without the expenditure of a disproportionate amount of Garda time.
