Five Metropolitan Police officers are facing a misconduct investigation in connection with the case of a woman who was found dead in Edinburgh months after going missing from her London home.
The death of Saima Ahmed, 36, remains unexplained after her body was discovered in the Scottish capital - 400 miles from her Wembley home - in January.
She was reported missing in August 2015 by her family, who say they have no idea why she would have travelled to Edinburgh.
The Independent Police Complaints Commission (IPCC) confirmed two officers had been notified they were under investigation for gross misconduct and three officers were served notices for misconduct.
The investigations are in relation to the conduct of the investigation and how information and lines of enquiry were handled.
The IPCC stressed the notices did not imply guilt.
Ms Ahmed was last seen on August 30 on CCTV, boarding a train at Wembley Central station instead of going to work.
Detectives believe she took further trains to Edinburgh, likely via Hemel Hempstead and Birmingham, although her exact route is not known.
There is an unconfirmed sighting of her at Portobello Beach around the end of August. Her remains were found at Gogar Mount House on January 9.
Police Scotland believe the librarian died close to the time she disappeared but post-mortem examinations have resulted in an ''unascertainable'' cause of death.
Family members claimed Met officers initially failed to take the case seriously despite her disappearance being ''totally out of character''.
