Uber driver Mohiussunnath Chowdhury, 27, from Luton who brandished a Samurai sword at police outside Buckingham Palace back in August of last year will face a retrial after a jury was unable to reach a verdict.
Chowdhury drove his blue Toyota Prius at a police van. The two officers present were able to spray him with CS gas and apprehend their attacker who was in possession of a four-foot blade.
It is believed Chowdhury had left his home with the sword and a blade sharpener and set out to peruse an attack. The incident took place at around 8:30pm outside the Queens Palace.
A jury at the Old Bailey was unable to reach a verdict on one count of preparing to commit an act of terror.
Chowdhury was heard shouting "help me Allah Akbar" during the incident and has said he was feeling lonely and depressed and only wanted to get himself killed by threatening the police officers with the sword.
Mrs Justice Bobbi Chema-Grubb discharged the jury after almost 11 hours of deliberation with no verdict.
Prosecutor Timothy Cray said the Crown would be seeking a retrial.
Chowdhury denied one count of preparing to commit an act of terror.
