BERLIN (AP) — Police in western Germany are appealing for help in cracking a potentially very cold case.
Authorities say about 60 containers of bull sperm were stolen from a farm in the town of Olfen, 90 kilometers (56 miles) northeast of Cologne, late Monday or early Tuesday.
Police said in a statement Wednesday that while it's unclear how the rustle happened, the precious cargo needs to be supercooled with liquid nitrogen at minus-196 Celsius degrees (-320 Fahrenheit) so it isn't spoiled.
They are seeking tips from the public that might lead to the recovery of the sperm, which was intended for artificial insemination.
