Castrating Pablo Escobar's hippos
Witness History
Sep 28, 2022

When drug kingpin Pablo Escobar died in 1993 having built a billion dollar cocaine empire, he left behind a zoo. While his rhinos, giraffes, elephants and kangaroos were re-housed, the hippos were left in Escobar’s abandoned ranch in the Colombian countryside.

In 2007 they started turning up 100 kilometres away, frightening fishermen. Vet Carlos Valderrama was called in to tackle the problem. He describes to Josephine McDermott his experience of the first ever castration of a hippo in the wild.

Norway's WW2 railway sabotage plot

In May 1942, a team of Norwegian resistance fighters in occupied Norway were getting ready to blow up a railway carrying materials crucial to the German war machine.

Led by Lieutenant Peter Deinboll, a local from the area, they set out to execute what the Allied forces saw as the top priority sabotage operation in Norway at that stage in the war. Should they fail, allied planes would carpet bomb the village, including Deinboll’s hometown.

Lars Bevanger speaks to Lieutenant Deinboll’s nephew, Gunnar Deinboll Jenssen.
