Nigerian John Ogah (L), 31, stands in front of his godfather Italian carabinieri Nunzio Carbone (L), after being baptised by Pope Francis during the Easter Vigil at St Peter's basilica on March 31, 201 in Vatican. John Ogah is a Nigerian migrant-turned-hero after helping stop a thief until police arrived last year. Ogah asked the Rome police captain Nunzio Carbone who handled his case to be his godfather. Christians around the world are marking the Holy Week, commemorating the crucifixion of Jesus Christ, leading up to his resurrection on Easter. / AFP PHOTO / Andreas SOLARO
