Chilean police arrested three suspects who are believed to have orchestrated the terrorist bombing of Sept. 8 in the country's capital Santiago. The arrest involved hundreds of officers storming six households around the city and the suspects are being held as the police continue investigating.

According to Interior Minister Rodrigo Penailillo announced that two men and one woman had been arrested in connection to the bombing that happened more than ten days ago in the shopping area at the Escuela Militar subway station, reports the BBC.

The bombing attack injured 14 people when the homemade bomb, a fire extinguisher filled with gunpowder, detonated a little after 2 p.m., according to Vice News. At the time, no one had claimed responsibility; however, the bombing was the last in a series of bombing attacks around the Chilean capital.

The Sept. 8 attack happened in the wealthy district of Los Condes three days before the anniversary of the right-wing military coup that overthrew the Allende government in 1973.

President Michelle Bachelet activated the country's anti-terrorism law as police began searching for the suspects.

In an early morning raid on Thursday, 200 Chilean federal police officers raided six homes in the districts of La Granja, La Pintana and San Bernardo and arrested Guillermo Durán, Natalia Casanova y Juan Flores, according to EFE. Police have identified Flores as the mastermind behind the bombing.

Prosecutor Raul Guzman told reporters he had asked the court to extend the suspects' detention while further scientific testing and inquiries continued. They will be held until Sept. 23 when it will be announced if they will be charged.

The police discovered the trio after investigating the debris from the blast, reports El Mercurio. Police investigators found the remnants of a receipt for the local public transport system card during the July 13 bombing. The police traced the card back to Flores.

The three are believed to be anarchists. Flores shouted, "Death to the police state!" when he was brought to court.
