Senior Scotland Yard officials fear Neo-Nazis are plotting a "spectacular" terrorist attack on Britain, the U.K.'s Daily Mail reported.
Surveillance of suspects have been increased and officials are monitoring their ability to carry out an attack that would "breakdown in community cohesion," according to the newspaper.
"I fear that they will have a spectacular...They will carry out an attack that will lead to a loss of life or injury to a community somewhere," Commander Shaun Sawyer told the Mail. "They're not choosy about which community."
Officials say the goal of the attack would be to fuel racial tension.
