Information footnote

It was widely reported in the aftermath of the Brussels attacks that a taxi driver had tipped off the police about where he had picked up the bombers after being suspicious about the journey in light of the bombings, leading the police to their base. That now appears to be false (New York Times) --

But the driver was said to have alerted the police only after a photograph of the suspects in the attacks was released hours later, raising questions about whether the police had perhaps already had the building in their sights but, for some reason, had not moved in and smashed through the front door to the sixth-floor apartment until it was too late.
