Suicide prevention situations are often very tricky - but as a recent incident at Wood Green shows, heavy-handed policing does not help.
A video of the incident has gone viral on social media. A passenger had made it known that they wanted to end their life, and staff and bystanders went into action to protect and reassure them.
But when the BTP attended, they restrained the person with unnecessary force, which led to a pile-up of bodies at the bottom of the escalators, with several people being injured.
Unfortunately, there are many documented cases of the police using excessive force with people who are experiencing mental health problems, but it is particularly alarming for us as Tube workers for this to happen in our workplace, and for our workmates to be affected so directly. We expect to see our unions taking this up with the employer and the BTP.
