Dubious statement English serial killer Peter Sutcliffe the Yorkshire Ripper was arrested in Sheffield ending one of the largest police investigations in British history This is a rather ridiculous statement Why do you think it takes up to two years to bring murder cases to court A large amount of police investigation finding witnesses scientific testing of evidence etc occurs after the suspect has been arrested An arrest certainly does not end the police investigation It may well end the police man hunt but if that is the case then that it what the article should say
