Rio de Janeiro has had its fair share of bad publicity leading up to the 2016 Olympics, and it seems to be getting worse.

The Zika virus is causing athletes and spectators to bow out of the Games. Australia demanded higher security for athletes after a Paralympian was robbed at gunpoint. The Rio testing lab that was supposed to conduct anti-doping analyses was shut down indefinitely by the World Anti-Doping Agency.

Now, according to an AP report, there is concern that there could be massive issues regarding both security and mobility in Rio, due to a lack of funding.

In an interview with Brazilian paper O Globo, Rio's acting governor Francisco Dornelles said that the state is still awaiting a $860 million payout from the federal government, and warned that without the money police patrols may slow considerably by the end of the week due to a lack of gas money.

"How are people going to feel protected in a city without security? I'm optimistic about the games, but I have to show reality. We can have a great Olympics, but if some steps aren't taken, it can be a big failure."

Protesters have already been seen at the Rio airport, warning incoming tourists of the perceived lack of security.

Dornelles, who took over for Governor Luiz Fernando Pezão earlier this year after Pezão was diagnosed with non-Hodgkin's lymphoma and took a medical leave, also showed concern for the metro line that was supposed to shuttle tourists to and from various events.

The metro line was scheduled to be functional in late 2015, but still is not ready. The opening ceremony is on Aug. 5.

"I've said that without security and without the metro there will be difficulties," Dornelles was quoted as saying.

Dornelles' comments came after two Rio police officers were killed this weekend. There have been 49 Rio de Janeiro officers killed since the start of the year, according to O Globo.

A day earlier, Gisele Palhares Gouvea was shot in the head in her car as she entered one of Rio's main expressways on her way to her home.

Asked about Gouvea's slaying, Dornelles responded, "What a disaster. The security crisis is very serious."
