AKIPRESS.COM - Spanish police erected 800 checkpoints across the region of Catalonia on Sunday — part of a massive manhunt for a Moroccan-born man they suspect was the driver of the van that killed 14 and injured scores in Barcelona last week.

Authorities could not say whether Younes Abouyaaqoub, 22, was still in Spain or had crossed the border into France, but they were clearly frustrated that he continued to elude police, Washington Post reported.

“We don’t know where he is,” regional police chief Josep Lluís Trapero said at a news conference in Barcelona, adding that the terrorist cell had planned a “much more serious attack” that probably was thwarted by an accidental explosion Wednesday at a house used to assemble components for a bomb.
