A French judicial official says that investigators are trying to verify whether a leading suspect in the Nov. 13 Paris attacks bought about 10 detonators at a specialized store outside Paris in September or October.

Investigators are in the process of checking whether the detonators were sold to Salah Abdeslam, who is on the run and the subject of a massive manhunt, the judicial official said. The official was not authorized to speak publicly about the matter and asked not to be identified.

The daily newspaper Le Parisien reported on Saturday that the manager of a company in the Val d'Oise region, northwest of Paris, had recognized Abdeslam after wanted posters were issued and contacted police to say he had sold electrical detonators to him. The paper quoted unnamed sources close to the case.

The judicial official said investigators have been checking whether the man reported to have bought the detonators was, indeed, Abdeslam, one of two people who escaped after the attacks that killed 130 people.

French Interior Minister Bernard Cazeneuve says that nearly 1,000 people so far have been barred from entering France since border controls were put in place just after the Nov. 13 Paris attacks that killed 130 people.

Cazeneuve, speaking on Saturday in the eastern city of Strasbourg, said that nearly 15,000 police, gendarmes and customs officials are manning France's borders, notably the northern borders that are entryways to Belgium, where the three teams of attackers started their deadly journey, and to Germany.

The borders were re-enforced in the run-up to the COP21 climate talks that start on Monday and in the wake of the attacks. Cazeneuve noted the "very high threat level" that has yet to abate.

Besides those barred from entering France, 300 people have been placed under house arrest as part of a state of emergency. Two dozen of the 300 are considered potential threats to public order during the two-week climate summit.
