The head of Portugal’s SEF immigration and borders service resigned on Wednesday after months of backlash over the fatal beating of a Ukrainian man detained at Lisbon airport for trying to enter the country without a valid visa. Ihor Homenyuk died in March at an airport detention centre run by SEF where he was taken after refusing to board a flight out of the country. Three immigration officers accused of beating up Homenyuk with an expandable baton after the man became “agitated” over his detention, have been charged with murder.
