Counter-terror chief Mark Rowley revealed the name in a briefing Friday outside Scotland Yard in which he also said there were two other significant arrests. That brought the total number of people in custody for the Wednesday attack to nine.

The attacker was born in southeastern England and had most recently been living in the central city of Birmingham.
