Boston police said Wednesday that no arrest had been made in the Boston Marathon bombing after several media reported that a suspect was in custody in connection with the attack. 'Despite reports to the contrary, there has not been an arrest in the Marathon attack,' the police said on their Twitter feed. A police dispatcher later told officers over the radio that 'to our knowledge' no arrest had been made. The US Attorney's office also said there had been no arrests. CNN and other broadcasters reported that an arrest has been made after surveillance video showed images of a suspect at the crime scene. The Boston Globe had reported an arrest was 'imminent'.
