Two other women and three men received various injuries in the attack, Scotland Yard said. Two from the group remain in hospital while the other three people have since been discharged, the force added. After receiving treatment in hospital the arrested man is now in police custody. The Met's assistant commissioner for specialist operations, Mark Rowley, said the force's homicide command was leading the investigation into the attack, with support from the counter-terrorism unit.
