PARIS (AP) -- French authorities on Tuesday questioned a top suspect linked to attackers who terrorized Paris, while Belgium's capital remained locked down under threat of a possible similar attack.
Jawad Bendaoud, the only person in France known to be facing potential terrorism charges directly linked to the Nov. 13 Paris attacks that killed 130 people and wounded hundreds, was handed over Tuesday morning to an anti-terrorism judge in Paris, according to a judicial official. Bendaoud was detained last week for providing lodging to the suspected mastermind of the attacks in an apartment in the Paris suburb of Saint-Denis.
Police raided the apartment Nov. 18, and three people were killed — including suspected attacks orchestrator Abdelhamid Abaaoud, a female cousin and one other. Bendaoud acknowledged in a television interview giving shelter to two people from Belgium, but said he didn't know who they were or what they planned. Bendaoud, 29, told BFM television, "I didn't know they were terrorists. I was asked to do a favor. I did a favor, sir."
He must be either charged or released Tuesday.
French Interior Minister Bernard Cazeneuve told lawmakers on Tuesday that 124 people had been handed preliminary charges since a state of emergency was imposed hours after the attacks, following more than 1,230 searches in which 230 weapons were recovered. He didn't, however, specify what the charges were or if they were linked to the attacks.
In Belgium, four people have been handed terrorism charges since the Paris attacks, which have been traced to a network of people with ties to both France and Belgium.
Brussels remained at its highest alert level Tuesday, after Belgian Prime Minister Charles Michel cited a "serious and imminent threat" to the city, which houses the headquarters of the European Union and NATO. Belgium's crisis center said the alert level would only change if a significant breakthrough warranted it.
Increased security measures in the wake of the massacre in Paris have virtually shut down the Belgian capital, with the subway system, many shops and schools remaining shut. Michel said that despite the continued high alert, schools would reopen on Wednesday.
Businesses in Brussels were starting to feel the pain, and while few question the government's need to protect the public from a potential attack, some shop owners said the shutdown was too extreme.
"It's not a very good decision," said Esther Willems, assistant manager at the Galler chocolate shop in the heart of Brussels' city center. "In the last two days, we have only had about 10-11 clients" compared with about 100 normally. Willems said she hoped things would improve Wednesday.
Many questions remain unanswered as investigators try to piece together what happened in Paris on the night of Nov. 13 and who might still be at large.
Only one fugitive has been publicly named: Salah Abdeslam, who crossed into Belgium the morning after the attacks.
A street cleaner in a Paris suburb found an explosive vest Monday near the place where Abdeslam's cellphone was found, raising the possibility that he aborted his mission, either ditching a malfunctioning vest or fleeing in fear.
Authorities said the device, which did not have a detonator, was found in the southern Paris suburb of Montrouge. A police official said the vest contained bolts and the same type of explosive used in the Nov. 13 attacks.
France's security chiefs held a meeting Tuesday about protection for next year's European soccer championships, being hosted in cities around France. Concerns are especially high because one of the targets of the Nov. 13 attacks was the country's national stadium.
Interior Minister Bernard Cazeneuve also held a meeting with French Muslim leaders, who have denounced the attacks and expressed concern about a backlash on France's largely moderate, 5-million-strong Muslim community.
Also Tuesday, French police released a photo of a dog killed in the Saint-Denis apartment siege, a 7-year-old Belgian shepherd named Diesel. The National Police said Diesel, a SWAT team assault dog, was "killed by terrorists."
