On February 3, 2014 at approximately 12:32 am Transit Police officers working in Area 1 received a radio call to respond to MBTA Back Bay station for a report of a man exposing himself and committing a lewd act on the Orange Line platform. Officers were also provided with a description of the offending male subject by the reporting party. Upon arrival officers located a male matching the description furnished and approached him. The male provided the officers with several false names and social security numbers. Ultimately officers were able to ascertain the man's true identity and it became obvious to the officers why he was attempting to mislead them. Daniel Williams, 55 of Boston is a Level 3 Sex Offender who was in violation of the registration laws. Williams was placed into custody for Failing to Register as a Level 3 Sex Offender and was transported to Transit Police HQ for the arrest booking process. It is expected Williams will be arraigned sometime today in Boston Municipal Court-Central Division.
