Item ‘that looks like an explosive vest’ found in Paris suburb

An item “that looks like an explosive vest” was found in the Parisian suburb of Montrouge, the Paris Police Prefecture said today, and investigators are at the scene to determine if it can be linked to the Paris attacks.

A cellphone signal for Salah Abdeslam, a fugitive wanted in connection to the Paris attacks, was also located in Montrouge on the night of the Nov. 13 massacre, the Paris Police Prefecture added.

Meanwhile, in Belgium, the city of Brussels will remain on the highest level terror alert through next Monday, the Belgian Prime Minister said today, repeating that officials believe the terror threat there is serious and imminent. The schools and subway are currently closed, but set to reopen Wednesday.

The rest of Belgium will stay at a threat level of 3 out of 4, the prime minister said.

Overnight, police carried out a series of raids across Belgium and detained 21 people, but failed to capture Abdeslam, whose whereabouts remain unknown, authorities said.

Of the 21 people detained, one was formally charged with participating in the Paris terrorist attacks, the prosecutor’s office in Belgium said today. This was the fourth person charged in Belgium since the attacks on Nov 13.

Of the 21 detained, 17 were released without charges and three remain in custody for questioning, the prosecutor’s office said.

The Belgian prosecutor’s office told ABC News today that the overnight raids revealed to authorities that Abdeslam is not alone and authorities will continue to look for Abdelslam and work to identify and arrest those around him.

Officials are working to arrest those involved in the Paris attacks as well as stop those who may be plotting new attacks, the Belgian prosecutor’s office said. Officials said they have reason to believe that since some attackers were from the Brussels area, an attack is most likely in Brussels, the Belgian prosecutor’s office added.
