MOSCOW (Sputnik) — The last suspect was detained with the help of military police in Comodoro in the western-central Brazilian state of Mato Grosso. He was identified as Leonid El Kadre de Melo, a mechanic, according to O Globo journal.
"Operation Hashtag was concluded overnight," the federal police tweeted, adding the last arrest warrant was served and the suspect would be sent to an undisclosed federal prison after a hearing.
This was the twelfth and the last arrest, which wrapped up last week's security operation, dubbed Operation Hashtag. It targeted a group of Islamist sympathizers who had allegedly been discussing an attack on the Rio Olympic Games via mobile messengers.
