A man's appeared in a UK court over a stabbing attack on an eastern England train over the weekend

A train worker who rushed to stop the attack remains in a critical but stable condition in hospital.

32-year-old Anthony Williams has appeared in court, on 10 counts of attempted murder relating to the attack.

He also faces a separate charge of attempted murder, relating to an incident in London hours beforehand.

Police say they're also investigating his potential involvement in three other incidents, including the stabbing of a 14-year-old earlier this week.
