What happened
Alison Anderson, a community psychiatric nurse, was on a routine visit to the home of Angela Senior in Streethouse, near Pontefract. Senior had been drinking and had not taken her regular medication.
During the visit she produced a knife and refused to let the nurse leave. She told her: “now you know what it feels like not to see your children”. She took the nurse’s bag and phone, said she would use the nurse’s car to find and stab her former partner, and took £45 from the bag to buy more alcohol. The nurse was held for about half an hour.
When Senior became ill after taking some of her tablets, the nurse snatched a phone and ran upstairs to call the police. Senior followed with the knife, attacked the television with it, and cut her own wrists with broken glass. She opened the front door only when she saw officers outside, and told them she had been feeling suicidal.
The outcome
Senior, 41, of George Street, Streethouse, pleaded guilty at Leeds Crown Court to false imprisonment and theft, and was jailed for three years. Recorder Richard Mansell QC said he considered her dangerous because of her mental health problems, which included depression and an emotionally unstable personality disorder.
No source publishes the trust’s risk assessment, the supervisor’s instructions, or any review after the visit. The nurse’s employer is not named in the reporting.
What went wrong
This was not an attack at the door. It was containment: the client shut the exit, then removed the means of getting away from it. Bag, phone and car went in that order, and the threat was made explicit.
The nurse’s escape was improvised. It worked because a phone was within reach and there was an upstairs room to call from. The source describes no vehicle check-in, no time limit on the visit and no colleague watching a clock. On a visit to a known client, that failure stays silent until it is not.
What it teaches
Containment is a separate risk from assault, and it needs a separate control. A client who takes your keys, your phone or your bag has taken your exit without laying a hand on you. The control is to keep all three on your body, and to keep the conversation within reach of the door.
The second control is the clock. Someone outside the house should know when the visit started, when it should finish, and what to do when the worker does not call in. Half an hour is short. It is also long enough for nobody to notice.
Questions for the room
- Where are your phone, keys and bag right now? Can you reach the door without moving past the client?
- A visit is due to end at 15:00 and the worker has not called in by 15:20. Who acts, and what do they do first?
- What do the notes tell you about this client’s drinking and medication today, and when were they last checked?
- Your client tells you that you cannot leave. What is your next sentence?
Evidence and limits
Confidence: probable. One outlet was read in full, the Yorkshire Post report of the sentencing at Leeds Crown Court, and re-read live on 20 October 2026. The record is marked probable because the case rests on a single source with no second press account to check it against, so the detail here is one reporter’s account. The quoted remark, Senior’s age, address, plea and sentence all come from that report. The nurse’s own account is not in the public record, and no source says what her employer had told her.
Our lone working training sets out the visit protocol this case turned on: the check-in and the exit.
