A teenage boy from Hertfordshire as been arrested on suspicion of a terror offence.
The 17-year-old was arrested at an address in the county on Tuesday on suspicion of encouraging terrorism.
The investigation relates to alleged offences linked to extreme right-wing terrorism, the Met Police said.
He was taken to a London police station and has since been bailed to a date in mid-July.
The operation was led by the Met’s Counter Terrorism Command, with support from the Eastern Region Specialist Operations Unit (ERSOU) and Hertfordshire Constabulary.
Detective Chief Superintendent Dominic Murphy, of the Met’s Counter Terrorism Command, said: “Across the country, police are working hard to try and prevent young people from being radicalised, and acting quickly when it is suspected that offences have been committed.
“Police rely on information from the public in our mission to tackle terrorism.
“If you see or hear something unusual or suspicious and think someone may be engaging in terrorist activity, trust your instincts and contact police.”
