The poor tortoise from the Twycross zoo got flipped on it’s back, presumably by another tortoise. People (including myself) were trying to find staff to flip it back again, but nobody was found. Even after calling the reception and the promise of some one coming nothing happened. So another zoo visitor saved the day, by putting herself at risk ( they’re bite can be quite severe apparently) climbed into the enclosure and flipped the tortoise back.
On a later visit, it looked like they separated the tortoises.
