POLICE have foiled a suspected terror attack on soldiers protecting King Charles.
Military personnel at a barracks just a stone’s throw from Windsor Castle were warned not to leave the grounds in uniform after a man was arrested.
The alert remained in place for two days at Victoria Barracks, home to the 1st Battalion Coldstream Guards.
A source said: “The suspect is feared to have been plotting an attack.
“Police informed bosses at the barracks and measures were taken immediately despite him already being in custody.
“It was a huge security scare. But it was in the interests of everyone’s safety.”
Thames Valley Police first arrested the 20-year-old in Slough, Berks, last week on suspicion of possessing an offensive weapon and arson at the nearby Salt Hill Activity Centre.
While in custody on Sunday, he was re-arrested on suspicion of preparation of terrorist acts.
The investigation is now being led by Counter Terrorism Policing South East.
The suspect is believed to be a “lone actor” and no other arrests have been made.
Police said they were stepping up patrols to reassure the public.
The Ministry of Defence was approached for comment.
