CAIRO (AP) -- Egyptian security officials and state television say several wanted Muslim Brotherhood leaders have been arrested after troops stormed a protest camp of supporters of ousted President Mohammed Morsi.
The officials say police detained senior Brotherhood leaders Mohammed el-Beltagy, Essam el-Erian, group spokesman Ahmed Aref and its chief theologian Abdel-Rahman el-Bar.
Also captured is hard-line cleric Safwat Hegazy, who is close to the Brotherhood.
El-Beltagy, el-Erian and Hegazy are wanted by prosecutors to answer allegations of inciting violence and conspiring to kill protesters calling for Morsi's ouster.
The five were arrested shortly after police completed its control of the camp in Cairo's eastern Nasr City district.

Riot police backed by armored vehicles, bulldozers and helicopters Wednesday swept away two encampments of supporters of ousted President Mohammed Morsi, sparking running street battles elsewhere in Cairo and other Egyptian cities. At least 149 people were killed nationwide, many of them in the crackdown on the protest sites.
Vice President Mohamed ElBaradei, a Nobel Peace Prize laureate and pro-reform leader in the interim government, resigned in protest over the crackdown as the military-backed leadership imposed a monthlong state of emergency and nighttime curfew.
Clashes broke out elsewhere in the capital and other provinces, injuring more than 1,400 people nationwide, as Islamist anger spread over the crackdown on the 6-week-old sit-ins of Morsi supporters that divided the counrty. Police stations, government buildings and Coptic Christian churches were attacked or set ablaze.
The assault to take control of the two sit-in sites came after days of warnings by the interim administration that replaced Morsi after he was ousted in a July 3 coup. The camps on opposite sides of the Egyptian capital began in late June to show support for Morsi. Protesters -- many from Morsi's Muslim Brotherhood -- have demanded his reinstatement.
The violence drew condemnation from other predominantly Muslim countries, but also from the U.N. and the United States, which said the crackdown will only make it more difficult for Egypt to move forward.
The smaller camp was cleared relatively quickly, but it took hours for police to take control of the main sit-in site, which is near a mosque that has served as the epicenter of the pro-Morsi campaign.
Police dismantled the main stage of the lager camp near the Rabaah al-Adawiya Mosque in the eastern Cairo district of Nasr City, the official MENA news agency said. An AP reporter saw hundreds of protesters leaving the sit-in site carrying their personal belongings.
Smoke clogged the sky above Cairo and fires smoldered on the streets, which were lined with charred poles and tarps after several tents were burned.
In imposing the state of emergency, the government ordered the armed forces to support the police in restoring law and order and protect state facilities. The nighttime curfew affects Cairo and 10 provinces.
The Egyptian Central Bank instructed commercial banks to close branches in areas affected by the chaos, a sign of alarm that the violence could spiral out of control. The landmark Giza Pyramids and the Egyptian Museum also were closed to visitors for the day as a precaution, according to the Ministry of Antiquities.
The turmoil was the latest chapter a bitter standoff between Morsi's supporters and the interim leadership took over the Arab world's most populous country. The military ousted Morsi after millions of Egyptians massed in the streets at the end of June to call for him to step down, accusing him of giving the Brotherhood undue influence and failing to implement vital reforms or bolster the ailing economy.
The coup provoked similar protests by Morsi's backers after he and other Brotherhood leaders were detained as divisions have deepened, dealing a major blow to hopes of a return to stability after the 2011 revolution that toppled autocratic ruler Hosni Mubarak.
Morsi has been held at an undisclosed location. Other Brotherhood leaders have been charged with inciting violence or conspiring in the killing of protesters.
"The world cannot sit back and watch while innocent men, women and children are being indiscriminately slaughtered. The world must stand up to the military junta's crime before it is too late," said a statement by the Brotherhood's media office in London emailed to The Associated Press.
ElBaradei, a former head of the U.N. nuclear watchdog agency, was named only last month as interim President Adly Mansour's deputy for foreign relations.
In his resignation letter, he wrote that he is not prepared to be held responsible for a "single drop of blood," and that only more violence will result, according to a copy that was emailed to The Associated Press. He said Egypt is more polarized than when he took office.
