A man has been arrested on suspicion of terrorism offences in the Clifton area of Bristol.
The 33-year-old was detained by Counter Terrorism Police at around 11pm on Monday 9 December.
Police say the arrest was linked to Islamist-related terrorism but stressed the incident was not related to the London Bridge terror attack on 29 November.
The man remains in police custody, and officers are carrying out a search of the house in Clifton.
At around 11pm, counter terrorism detectives arrested a man on suspicion of terrorism offences and are currently carrying out searches at a residential property in Bristol. This was part of a pre-planned operation by Counter Terrorism Police South East working alongside colleagues at Counter Terrorism Police South West. I would like to thank the local community for their patience whilst we carry out searches and continue our investigation.
Superintendent Andy Bennett, of Avon and Somerset Police, said the force would have "an increased policing presence in the local area".
