BIRMINGHAM, England (AP) — The 52-year-old Briton identified as the Westminster Bridge attacker had a raft of convictions — including assault, weapons possession and public order offenses — spanning two decades, London police said. Khalid Masood, a U.K.-born resident of the West Midlands in central England, was once investigated for extremism by British authorities but was not currently on a terrorism watch list. Many suspects in British terrorist attacks or plots have had roots in Birmingham, England's second-largest city, and several local mosques have been linked to extremist clerics.
