CAIRO (AP) -- Egypt's top prosecutor on Monday ordered an investigation into a complaint that satirist Bassem Youssef, known as the country's "Jon Stewart," harmed national interests by ridiculing the country's military in his first program of the season.
The decision could be a prelude to further action against the popular comedian such as questioning and a possible trial, posing a litmus test for the deeply divided country's tolerance for criticism of the military and its leaders nearly four months after Islamist President Mohammed Morsi was toppled in a coup.
Critics have expressed concerns that the military could expand a deadly crackdown against the Muslim Brotherhood, which won a series of elections after the 2011 revolution but came under allegations it was trying to monopolize power.
While most Egyptians appear to support the military's actions against the Islamists, the detentions earlier this year of an Egyptian labor lawyer and a journalist prompted rights activists to complain the military-backed government was trying to silence any dissent.
Youssef could not be reached for comment on the complaints and has remained largely silent on the issue, although he took to Twitter after Friday's show to remind the public: "It is only an episode in a program, people."
Youssef's "Daily Show"-style program has brought a new type of political satire to Egypt, and he gained plaudits for mercilessly skewering Morsi and his Islamist supporters for mixing religion and politics and for failing to implement much-needed reforms amid more than two years of turmoil following the ouster of autocrat Hosni Mubarak.
But the first show of the season faced a delicate balance as Youssef risked angering his mainly liberal fan base by criticizing the new military-backed government and army leader Gen. Abdel-Fattah el-Sissi, lionized in the media as a hero for removing the Brotherhood from power. Anything else would be seen as caving to pressure.
The 39-year-old surgeon-turned-satirist answered in Friday's episode of "El-Bernameg" -- Arabic for "The Program" -- by taking aim at the over-the-top, pro-military fervor sweeping Egyptians and jabs at el-Sissi with a series of jokes and skits.
The office of chief prosecutor Hesham Barakat said Monday it was investigating Youssef on a complaint that he disturbed the peace, harmed public interests, created chaos, sowed sedition and threatened security and peace. It also alleged that Youssef inappropriately ridiculed the Egyptian people, the armed forces as well as all "honorable national icons" without respect for traditions and customs.
Barakat's office received several complaints against Youssef after the program, but chose just one to be investigated in line with standing policy to focus on the best written and documented allegations.
The show comes against the backdrop of rising bitterness between the sides supporting and opposing Morsi, who has been detained and held at an undisclosed location since July 3. The ousted leader is scheduled to go on trial on Nov. 4 for allegedly inciting supporters to kill protesters outside his presidential palace in Cairo last December.
Many Egyptians are watching what happens to Youssef as a measure of whether the government installed by the military after Morsi's July 3 ouster is serious about shepherding the country toward democracy and freedom.
But activists said the fact that Barakat ordered an investigation into the complaint barely three days after the program was aired did not bode well for Youssef.
Heba Morayef, Human Rights Watch's Egypt director, said that while ordering an investigation into a complaint is routine, publicizing the decision is perceived as a serious step that could lead to an interrogation and a formal indictment.
"He (Barakat) is clearly responding to public pressure, or pressure from someone in particular," she said, without specifying who that might be.
About two dozen military supporters, who say the crackdown is a small price to pay if the country is to defeat what they view as Brotherhood-inspired terrorism, staged an anti-Youssef protest on Monday outside a Cairo courthouse, trampling on posters of the comedian and chanting slogans in favor of el-Sissi.
Youssef also faced legal action for his comedy during Morsi's year in office. The president's supporters sued him for insulting the presidency and Islam. He was questioned for hours by prosecutors, but was not charged with any crime.
Before returning to the air after a four-month absence, Youssef predicted in an article that he will continue to be pursued legally by his new critics "who allegedly love freedom dearly -- when it works in their favor."
In another example of how the political divisions are affecting everyday life, relatives and state media said an Egyptian kung fu gold medalist was suspended by the sport's national federation because he displayed an Islamist symbol showing support for Morsi during a tournament in Russia.
