According to BBC News, the Athletics Integrity Unit has provisionally suspended Peres Jepchirchir, the reigning world women's marathon champion, after a sample tested positive for EPO.
The Guardian, which carried a report from Agence France-Presse, said the Athletics Integrity Unit announced the suspension on Friday and is investigating the case. Its headline described the matter as a "positive doping test." The newspaper identified Jepchirchir as a 33-year-old Kenyan who won Olympic gold in the Covid-delayed Tokyo Games in 2021. The Guardian also described the case as a fresh setback for Kenyan athletics.
Both BBC News and The Guardian describe the suspension as provisional. The Guardian said the investigation concerns a sample that tested positive for EPO, and BBC News gave the same finding in its summary.
The summaries available for this report do not say whether Jepchirchir has responded to the suspension, when the sample was taken, or what steps will follow the investigation. The Guardian's summary ends partway through a sentence, so the full article may contain further details that were not available for this report.
