London - Jamaican sprinter Usain Bolt says Russian athletes being banned from the Rio de Janeiro Olympics will "scare a lot of people" thinking about doping.
A Court of Arbitration for Sport ruling on Thursday confirmed an IAAF ban on Russian track and field athletes from competing at the Rio de Janeiro Olympics.
Bolt, the winner of six Olympic gold medals, says "this will scare a lot of people, send a strong message."
The IOC is also mulling whether to follow the IAAF's decision and ban the entire Russia team from Rio over allegations of state-sponsored doping.
Bolt says recent actions by authorities show that "if you cheat or if you go against the rules" then "serious action" will be taken.
The world's fastest man was speaking in London ahead of a Diamond League meet where he will compete in the 200m on Friday.
