48 live rare African tropical fish which were being transported from the Natural History Museum have been found, after going missing on a train journey. The fish were being transported from London to Hull, but were taken off the train by mistake at Peterborough.
The fish were being transported in a case to the University of Hull for research purposes by post-graduate scholar, Kai Winkelmann. But someone offloaded them at Peterborough.
Sergeant Steve Down said: "Mr Winkleman stressed time was of the essence to find the fish as they required specialist care and would very likely die if they weren't properly cared for in the next few hours.
"Officers quickly realised the scale of the problem and called BTP and rail staff colleagues at Peterborough and Kings Cross, and the fish were quickly tracked down at Peterborough, still alive."
Pioneering research by forensic scientists at King's College London could help police solve more murders where bodies have been dumped in suitcases. It focuses on how easily flies can reach the body through the zip of a bag.
The research aims to give detectives a better estimate for the victim's time of death. A word of warning, Emma Burrows' report contains pictures of the experiment.
The research means detectives are able to work out a better estimate for the victim's time of death - and to discovered whether the body has been moved. Jackie Sebier is a Detective Chief Inspector with the Metropolitan Police.

Murder squad detectives could glean vital information from groundbreaking scientific research on bodies that are dumped in suitcases. New research is being carried out at the Natural History Museum into how easily flies can access bodies in suitcases.
It's thought the research will give detectives a much more accurate time of death for the victim. Female flies lay eggs on the zip of a bag, which when zipped tightly takes longer for maggots to be able to enter the bag.
This could mean the difference between hours and days when teams are estimating a victim's time of death.
There have been a number of high profile investigations of this type in recent years, including the murder of Alexandra Kovacs whose remains were found in a trolley case in Hendon, north London, last month, and the death of care assistant Leah Questin in 2009.
The Duchess of Cambridge will be inspecting fossils, shells, even dinosaur teeth a little later when she visits the Natural History Museum.
On display there, artefacts from millions of years ago. The collection also includes the skull of a lion who once lived at the Tower of London. And a rather popular gorilla.
Liz Wickham had a sneak preview.
London Tonight goes behind the scenes at the Natural History Museum's preview of Science Uncovered.
It is an event which will give people the chance to get much closer than usual to the exhibits.
Some of which are not always on display.
The would also be able to talk to some of the scientists and experts who have earned the museum its reputation around the world. Emma Walden has been along for a special preview.
