If the suspect is released after bail, an extended period of bail may only be imposed once by a superintendent officer up to 3 months (except in SFO cases). In "exceptionally complex" cases, particularly those involving the Financial Conduct Authority or Serious Fraud Office, the period may further be extended by an appropriate decision maker (an officer of the FCA or SFO, if applicable, or otherwise a police commander or assistant chief constable) up to 6 months, subject to representations from the suspect. After that, further extensions of bail, up to 6 months at a time, require a warrant to be issued by a magistrates' court. The bail period is suspended for any day when the suspect is in hospital as an in-patient.
