One of five men suspected of criminal activity at Fairfield flybase in England contacted police an hour before an anonymous tip alerted authorities to masked individuals near the airport. Both BBC and The Times reported the development on Wednesday, noting the content of the initial call remains unknown. The five men were initially arrested on suspicion of terrorism, but have since been released. Searches of the suspects’ vehicles have not revealed any explosives. The nature of the suspected crime at Fairfield flybase is still unclear, with investigations ongoing following the anonymous tip and the suspect’s earlier police contact. Authorities continue to investigate the incident and determine the reason for both calls.
