International athletics officials have provisionally suspended the Kenyan winner of the 2021 Boston marathon, Diana Kipyokei, for violating anti-doping rules.

The Athletics Integrity Unit (AIU) also suspended her compatriot Betty Wilson Lempus.

In addition, both athletes were charged with tampering with the doping control process.

The AIU launched an investigation after a banned substance – triamcinolone acetonide – was found in samples they had provided.

Eight other Kenyan athletes have tested positive for the drug, compared with only two other runners in the rest of the world since 2021.
