SPANISH NEWSPAPER LA VANGUARDIA SAYS YOUNES ABOUYAAQOUB HAS BEEN ARRESTED

Meanwhile, earlier in the day, the mother of Abouyaaqoub, the man suspected of mowing down pedestrians in a van attack in Barcelona’s Las Ramblas tourist hotspot, killing 14 people and injuring 120, has called on her son to surrender to police. Until the alleged arrest, the 22-year-old Moroccan was being hunted by police, and according to some media reports, had fled north into France.

Abouyaaqoub was the only person unaccounted for in the investigation into an extremist cell of 12 people identified by Spanish police, force spokesman Albert Oliva told a local radio station on Sunday. Catalan police had put up scores of roadblocks across the province in a manhunt for Abouyaaqoub, but the suspect has so far eluded law enforcement.

"This person is no longer just being sought in Catalonia but in all European countries, this is an effort by European police," Joaquim Forn, the Catalan interior minister, told Catalan radio. He confirmed that police were almost 100 percent certain Abouyaaqoub was the driver in the attack. "Everything points to that," Forn added, as cited by Reuters.

"We have no evidence that he crossed the border, we think it would not have been easy, but we cannot rule out that he didn't cross any border," Josep Lluis Trapero, head of the regional police in Catalonia, told a news conference on Monday. He added that the search for the suspect is currently the top priority.

On Monday, police also released photos of Abouyaaqoub, who is thought to have plowed the van into crowds in Barcelona last Thursday.
