Suicide vest found in Paris raises possible link to suspect

The discovery raised the possibility that the suspect aborted his mission, either ditching a malfunctioning vest or fleeing in fear

A street cleaner found an explosive vest similar to those used in the Paris attacks near the place where a suspect's mobile phone had been found, raising the possibility that he aborted his mission, either ditching a malfunctioning vest or fleeing in fear.

The discovery of the vest came as Belgium's prime minister cited a "serious and imminent" threat justifying keeping the highest alert level operational for at least another week.

The security measures, already in place for three days, have severely disrupted normal life in the capital.

In France, police said an explosive vest -- without a detonator -- was found by a street cleaner in a pile of rubble in Chatillon-Montrouge, on the southern edge of Paris and a considerable distance from the sites of the attacks on the Right Bank of the Seine to the north.

A police official later said the vest contained bolts and the same type of explosives (TATP) as those used in the November 13 Paris attacks that claimed 130 lives and left hundreds wounded.

The device was found yesterday in the same area where a cellphone belonging to fugitive suspect Salah Abdeslam was located on the day of the Paris attacks but the vest has not been formally linked to him, said two police officials who spoke on condition of anonymity because they were not authorized to discuss the investigation.

Belgium-based terrorism expert Claude Moniquet, who has been in contact with both Belgian and French investigators since the attacks, laid out two possibilities: that Abdeslam became afraid of carrying out a suicide mission or, more likely he says, that he simply ditched a defective explosive vest.

Nervousness could have played a role in concocting a defective vest, but he said he doubted fear played a role for among Islamic State followers, "it is rare not to go to the end."

Moniquet said this was only theory since he had not yet spoken to investigators about the explosive vest find.

A manhunt is underway for Abdeslam, whose brother Brahim was among attackers who blew themselves up. He crossed the border into Belgium after the attacks, with French police stopping and interviewing him, before letting him go.

Belgian Prime Minister Charles Michel said Brussels, which houses the headquarters of the European Union and NATO, faced a "serious and imminent" threat that requires keeping the city at the highest alert level, while the rest of the country would stay at the second-highest level.

Belgium's crisis center said the alert level would only change if a significant breakthrough warranted it.
