Police have arrested 10 suspects in connection with a plan to commit terrorist acts during the 2016 Rio Olympics, according to Brazilian publication O Globo.

Brazil's Justice Minister Alexandre de Moraes announced the arrests on Thursday which were made in the states of Parana and Sao Paulo, just south of Rio de Janeiro, and said two more are being sought. These are the first arrests made under Brazil's new anti-terror law.

During his announcement, Moraes also added that the group had been in contact with ISIS through the internet.

More from CBS News:

Moraes says police acted because the group had been discussing the use of weapons and guerrilla tactics to potentially launch an attack during the Olympics, which begin Aug. 5.

The suspects are all Brazilian and had never traveled to meet with anyone connected to ISIS, authorities said..

The arrests were made in the southern states of Sao Paulo and Parana. Moraes says there were no specific targets for attack.

The group was reportedly using the messaging program, WhatsApp, to communicate. This comes two days after a Brazilian judge in Rio ordered the country's five wireless carriers to block WhatsApp messaging service.
