The world 5000m silver medalist already faces a two-year ban until 2026 for three setbacks in 12 months.
Mohamed Kathir was disqualified for four years for forgery.
The 26-year-old, who won silver at the 5000m world in Budapest last year, has already Serving a two-year ban for missing three doping tests in a 12-month period.
This four-year ban will run alongside his whereabouts sanction, extending Kathir’s ban from the sport until February 2028.
That means he will miss the next two world championships in Tokyo and Beijing, but will be able to participate in the LA 2028 Olympics.
Kathir, who is also a World 1500m bronze medalist and European 5000m silver medallist, was found to have falsified travel documents, particularly the travel itinerary, boarding pass and booking confirmation, in an attempt to mislead investigators as they probed the authenticity of his explanation for three omissions : doping tests within a year.
The AIU Disciplinary Tribunal said: “There is no doubt that Kathir presented a false version of events and altered documents. He did this to convince World Athletics that his failure on February 28, 2023 should not be considered as such.
“Under the circumstances, it is clear that Kathir committed an anti-doping rule violation by attempting to tamper/fraud.”
Kathir’s other two failures were on April 3 and October 10, 2023. As of October 10, his results were already disqualified.
“Gone are the days in athletics when the explanations offered in anti-doping cases are simply accepted at face value,” AIU chief Brett Clothier said.
“The vast majority of our elite athletes respect the strict rules and processes of the sport, and they should take to heart the actions that are taken to ensure a level playing field.”
Not only has Katir won three major medals on the track, she also holds the European indoor 3000m and 5000m records with times of 7:27.64 and 12:45.01 respectively.
The Spaniard’s records will still stand, however, as they all came before October last year.
