Nottingham triple killer Valdo Calocane's peculiar behavior before the attacks raises questions. In May 2021, he visited MI5 headquarters, asking to be arrested. This is despite the fact that he had not yet been diagnosed with paranoid schizophrenia, which he was later found to have. The inquiry heard that Calocane appeared calm and collected when officers attended the MI5 headquarters at Thames House. He was allowed to leave the area after being spoken to by the police. The incident raises questions about why he wanted to be arrested and what information he might have had. The inquiry is ongoing, with a focus on understanding the lead-up to the attacks and the potential warning signs that were missed.
