UK Police Arrest Man in London in Relation to Islamist Extremism

LONDON — British police say they have arrested a man suspected of being involved in preparing acts of terrorism.

Scotland Yard said the arrest of the 31-year-old man, who it did not identify, is linked to “extremist Islamist terrorism.”

The force said the man was detained at a London business address Tuesday and remains in custody as officers continued searches Wednesday.

Britain’s government said earlier this month there has been a substantial rise in the number of terrorism-related arrests — including an increase in the number of women and teens detained — in 2015.

The national terrorism threat level remains at “severe,” meaning an attack is highly likely.
