The fear that Turkish Cypriots were engaged in a military build up with weapons and men smuggled in from Turkey was behind restrictions that the Cyprus government imposed on freedom of movement of Turkish Cypriots in the period 1963–67. Greek Cypriot police committed what was called by the UN Secretary-General "excessive checks and searches", [1] while Turkish Cypriots claimed they suffered harassment by Greek Cypriot officers at control points, airports and government offices.[7] The Secretary-General also noted his concerns about arbitrary arrest and detention.
