Police raided an apartment complex in Goodmayes, in the greater London area, on Thursday, as part of a wider terror investigation throughout the city.
Police were seen entering the apartments amid loud banging noises. Police claim there were no shots fired during the operation.
Four men were arrested during the raids, which also took place in Leicestershire, all under suspicion of being “concerned in the commission, preparation or instigation of acts of terrorism.”
One suspect was reportedly bitten by a dog during the incident and subsequently taken to hospital.
