 MetCC operates out of three centres in Lambeth, Hendon and Bow.Historically, each of the Met's Borough Operational Command Units (BOCUs) had its own control room, known internally as the 'CAD Room' (for Computer Aided Despatch) which dealt with incoming non-emergency calls and with despatching police to all calls in that area.In addition, the Information Room at New Scotland Yard received 999 calls which were sent to the CAD Room to be dealt with.
