Police have released without charge all of the 12 people arrested in connection with the Westminster terrorist attack last week, strengthening investigators’ belief that Briton Khalid Masood acted alone when he killed four and injured more than 50.
A 30-year-old man arrested on 26 March in Birmingham on suspicion of preparation of terrorist acts and detained under the Terrorism Act was released on Saturday and faced no further action, police said.
Eleven other people previously arrested in connection with the investigation into the 22 March attack had previously been released with no further action. Masood’s partner, Rohey Hydara, was one of those individuals.
The four victims of the attack have been formally identified as Kurt Cochran, 54, an American tourist; Aysha Frade, 44, a teacher; PC Keith Palmer, 48; and Leslie Rhodes, 75, a retired window cleaner.
The inquests into their deaths opened and adjourned on Wednesday under the authority of the senior coroner for Westminster, Fiona Wilcox. A provisional date for the pre-inquest review was set for 19 May at the Royal Courts of Justice.
