Counter Terrorism Police are hunting a man who did not report to detectives.
Police say Ibrahim Magag - pictured above - may have used a taxi near Osnaburgh Street and Triton Street on Boxing Day to go to a new location.
Detectives say he 'absconded from a Terrorism Prevention and Investigation Measures notice (TPIM)'.
Police say Ibrahim Magag does not represent a direct threat to the British public at this time.
Anyone with information should contact Police.
