Ibrahim Sued was a Brazilian journalist and columnist for the Rio de Janeiro newspaper O Globo who became the central figure of the Ubatuba UFO fragments case in September 1957. Via an anonymous letter to his newspaper column he received metallic fragments allegedly recovered from a disc-shaped object that had exploded over Ubatuba. Sued forwarded the samples to researcher Olavo Fontes, who had them analysed — and thereby set in motion one of the earliest physical-evidence cases of international ufology.
- Brazilian journalist, columnist for the newspaper O Globo in Rio de Janeiro
- Received anonymous fragments from an allegedly exploded UFO over Ubatuba via a reader's letter to his column
- Published the anonymous letter on 14 September 1957
- Forwarded the metallic samples to the ufologist Olavo Fontes
- Laboratory analysis showed unusually high-purity magnesium
- The Ubatuba case as one of the earliest physical-evidence cases in ufology
- Fragments have been the subject of repeated chemical and spectrographic analysis for decades
For the UAP timeline, Sued is the journalistic trigger of one of the longest-studied physical-evidence cases in the world: without his column and the forwarding to Fontes, Ubatuba 1957 would probably have sunk into Brazilian local news, instead of becoming a permanent topic of isotopic analysis in several countries.
