Then publicly humiliated over a tannoy system for refusal.
Technically, the tannoy announcements and threats to get the transport police involved were because the lady with the scooter and her partner were filming the guard and saying that they would put it all over the internet, which is a bit more understandable. I was very shocked when I first read the news and thought the guard was threatening to call the police because she would not dismantle the scooter, but less surprised when I saw the videos, although still think he should not have identified her in the announcements.
Ultimately though I think that the lady with the pram should have folded it up, possibly with the help from the train guard, and the lady with the scooter should have been allowed to remain. I can understand the pram lady's frustration if it's true that she had been allowed to reserve the space, and it's apparent that the lady with the scooter did not attempt to make a reservation and was also sat in the pram lady's seat, but the space is intended for disabled people.
The facts are weird and complicated though, especially as the pram lady said that she couldn't hold the baby but was then filmed (albeit briefly) doing so. And pram lady's partner had apparently injured his wrist too?
