A man tackled by police near Buckingham Palace was armed with a 4ft sword and repeatedly shouted "Allahu Akbar" - God is greatest - during the struggle, Scotland Yard has said.
The force has revealed the suspect drove a blue Toyota Prius "deliberately" at a marked patrol car before being confronted by officers. He then reached for the weapon in the passenger footwell, police said.
CS gas was used during the arrest, in which three officers were injured.
Commander Dean Haydon, of the Metropolitan Police counter-terrorism branch, said the suspect "deliberately drove at a marked police vehicle and stopped in front of it".
He added: "Uniformed officers then confronted the driver of the vehicle and during that confrontation the driver reached for a 4ft sword that was in the passenger footwell. CS gas was used as part of the arrest and during the struggle the individual repeatedly shouted the words Allahu Akbar."
A 26-year-old man from the Luton area is in custody at a central London police station.
I think that safely counts out radicalised Anglicans.
