A fifth man has been arrested in Sheffield over an alleged plot for a Christmas terror attack, police have said.
The 21-year-old man was held under the Terrorism Act on Friday night, and two buildings in the city are being searched.
Four men were held in earlier raids carried out in Derbyshire and South Yorkshire on 19 December.
A Counter Terrorism Policing North East spokesperson said: “The 21-year-old man, from the Fir Vale area of Sheffield, was arrested on suspicion of being concerned in the commission, preparation or instigation of acts of terrorism under Section 41 of the Terrorism Act 2000.”
“The intelligence-led arrest was made in the Firth Park area of Sheffield at approximately 11pm on Friday evening.”
“Two addresses, a residential address in Fir Vale and a business address in Firth Park, are currently being searched by officers.”
Two of the four men first arrested – Andy Star, 31, and Farhad Salah, 22 – have been charged with one count of engaging in the preparation of an act of terrorism.
Both men are Kurdish Iraqis, and Star is the owner of the Mermaid Fish and Chip Bar on Sheffield Road in Chesterfield.
