The dramatic arrest in London this week of a prominent Romanian businessman’s son is raising questions about the European Arrest Warrant, which obliges member states to carry out arrests on their soil on the orders of foreign governments.
Human rights advocates say the Romanian government’s case against Alexander Adamescu is politically motivated, and critics argue British police should not be carrying out the dirty work of governments such as Romania, rated as one of the most corrupt in Europe.

The European Arrest Warrant forces countries to extradite people charged with things that are not in them. It also means that when Turkey joins the EU, the British government will have to extradite people to Turkey where they are likely to be tortured.
