THE arrest of Frederick West triggered one of the biggest police inquiries in recent times. West was detained on February 25 last year with his wife Rosemary by detectives investigating the disappearance of the couple's daughter, Heather, last seen alive aged 16 in 1987.
A day later, police using mini-diggers found Heather's remains buried under a patio in the back garden of West's home, 25 Cromwell Street. Within days, two more bodies were found in the garden.
More grim discoveries were to follow. On March 5, police using specialist electronic sensing devices found two more sets of human remains in the cellar at Cromwell Street. A day later a sixth body was found, also in the cellar area.
On March 7, searchers announced the discovery of a seventh body, also in the cellar. Nine bodies were eventually discovered at Cromwell Street. Another was found at West's old home in Midland Road, Gloucester. And two more were discovered in fields at Kempley, on the Gloucestershire border.
The significant events in the inquiry were: February 23, 1994 - Police obtain a warrant to search the rear garden at 25 Cromwell Street.
February 25 - Frederick and Rosemary West arrested on suspicion of murdering Heather West.
February 26 - First body (Heather West) found in garden.
