Info on the identity of the two suspects gets reported. One is a Nigerian with British passport, coming from a devout Christian family but then converted to Islam. The other so far is not being mentioned. Both are known to the police from earlier incidents. Investigation into them showed them to be no danger. Which again shows that this kind of guys cannot be profiled. The attackers in London some years ago, did not match terrorist profiles. The attackers in Madrid years ago also did not.
