Aniz Abraão David (Rio de Janeiro, 7 June 1937), better known as Anísio, is an operator in the illegal jogo do bicho lottery (popularly known as bicheiro) and the honorary president of the Beija-Flor samba school in Nilópolis.

From a humble start at the beginning of the 1960s, Anísio and his family became the masters of municipal political power, the controllers of bicho gambling in the Baixada Fluminense and the champions of Rio's carnival.

The purging of the small bicheiros, with the annexation of their selling points through intimidation and force, and the "takeover" of the Beija Flor samba school, opened up space for their social ascension and the strengthening of their power in Nilópolis.

[1][2] At the beginning of the 20th century, many Syrian-Lebanese immigrants settled in Nilópolis, among them the patriarchs of the Sessim and Abraão David families, who established themselves as local merchants in the 1920s.

With one of his younger brothers, Nelson Abraão David, as his right-hand man, he took over in the 1960s controlling the betting stalls in Nilópolis.

At the same time, Beija-Flor established itself among the elite of Rio's carnival, with expensive and luxurious parades, while the families aligned themselves with the military regime.

[8] Journalistic sources point to Anísio as the main leader of the organisation, which during the 1960s and 1970s expanded through a wide network in the Baixada Fluminense region, based on political guarantees obtained through the influence of then state deputy Jorge Sessim David, a member of the family's collateral branch, and the main person responsible for Abraão David and Sessim joining the military regime shortly after the 1964 military coup.

[13][14][15] Anísio and other bicheiros Antonio Petrus Kalil, or Turcão, and Capitão Guimarães were among 25 people arrested on April 12, 2007, during Operation Hurricane, for alleged involvement with illegal numbers games, bingo parlors and the distribution of slot machines.

Press reports suggest that Anísio, the president of Beija-Flor that won the competition, used bribes and a hitman to buy and intimidate members of the carnival jury.
