Police investigating Friday’s sword attack outside Buckingham Palace in London arrested a second man on Sunday, a statement said.
“The man was arrested on suspicion of being involved in the commission, preparation or instigation of terrorism at 10:15hrs (0915 GMT) today and he has been taken into custody,” the statement said.
Police added that the 30-year-old man was arrested at an address in West London.
Late on Friday, a man deliberately drove at a police van close to the
Queen’s official residence in London and was detained by three police officers, who sustained minor injuries.
The 26-year-old arrested at the scene remains in custody after a warrant for his detention until September 1 was granted, the police said.
