Rob Macaire was detained as demonstrations broke out over the shooing down of a Ukrainian airliner by Iranian forces and was subsequently called in by the foreign ministry in Tehran to explain his "illegal and inappropriate" presence at the event.
Raab said it was a "flagrant violation of international law".
