Five men were arrested early Friday morning and an additional man was arrested around noon by British police under suspicion of terrorism related to Pope Benedict XVI's visit to London.
British police raided a London garbage depot and arrested the first five men at around 5:45 a.m. U.K. time according to MSNBC.
Police were tipped off about the six Algerian street cleaners, ranging in age from 26 to 50, and have not released any details about the basis of the terrorism suspicion reported MSNBC.
The pope has not altered his state visit plans in any way after learning of the arrests, but his security does seem to have been reinforced, according to The New York Times.
The six men arrested under suspicion of terrorism against the pope were freed without charge Saturday night. MSNBC says that the six men had been overheard at the garbage depot planning an attack against the pope and Metropolitan Police were simply investigating what could have been a serious threat.
