Anthony Williams, 33, has admitted to multiple violent charges related to a mass stabbing on a train last year but continues to deny several attempted murder allegations. Williams, from Peterborough, was arrested on November 1 following the incident on a Doncaster to London service, which was compelled to stop in Huntingdon, Cambridgeshire.

During a pre-trial hearing held via video link from Rampton Hospital in Nottinghamshire at Cambridge Crown Court, Williams entered guilty pleas to 14 new charges. These include wounding with intent concerning ten men injured on the 6:25 p.m. LNER service from Doncaster. Additionally, he admitted to two further charges of wounding with intent and two counts of attempting to wound related to earlier incidents.

Williams also altered his plea in relation to seven existing charges. He admitted to using threatening words or behavior and possessing a bladed article in Peterborough on October 31. On the same day, he acknowledged stealing kitchen knives from an Asda store in Stevenage, Hertfordshire. Other admitted offenses cover possession of a bladed article at Silvertown station in east London on November 1, committing common assault on a train traveling between St Pancras and Biggleswade, and having a bladed article aboard the train from Doncaster. He also pleaded guilty to assault occasioning actual bodily harm against a police officer while in custody on November 2.

Despite these admissions, Williams denies 14 counts of attempted murder. These charges include allegedly attempting to kill ten passengers and staff on the LNER train to King's Cross, an attempted murder at Silvertown station, and the attempted murder of three individuals—a 14-year-old boy and two men aged 22 and 28—in Peterborough on October 31.

Williams faces trial, which is scheduled to begin next Monday. The hearing will address the remaining charges, including those to which he has entered not guilty pleas.
