Man on the bridge, live-streaming
You are the duty inspector at 03:10. A 28-year-old man is standing on the wrong side of the railings of a bridge over a dual carriageway and a railway line. He is holding a kitchen knife against his own throat and live-streaming on social media. About 40 people are watching on the bridge, some filming. His partner says he has schizophrenia, stopped his medication a week ago, and has been saying 'the police will have to kill me'. A train is due in 12 minutes; the line controller has not yet been told. You have two officers at the scene, one Taser-equipped officer en route, an ambulance 15 minutes away and a police negotiator 25 minutes away. It is raining and dark. The man's mother is also at the scene and is shouting at officers. The live-stream has 300 viewers and is being shared. The road is not closed.
1. What are your immediate command decisions in the first five minutes?
Read the worked answer
I would make the scene safe enough to preserve life. First, stop the trains: a call to the rail controller to impose an emergency stop on the line, because a train in 12 minutes is an immediate lethal risk. Second, close the road under the bridge to remove traffic and give the negotiator and ambulance space. Third, establish an inner cordon and move spectators back, using officers to stop filming close up and to identify the live-stream. Fourth, designate one communicator; I would not have the mother shouting across the cordon. I would have an officer engage the mother, take her information and keep her back. Fifth, request the negotiator and ambulance and confirm the Taser officer's location, but I would not make Taser the plan. I would brief that the objective is containment and dialogue. The reasoning is that the man's threat is to himself, the environment adds lethal hazards, and early rail and road closure are the highest-consequence actions I can take.
2. What legal framework and safeguards apply to any use of force or detention?
Read the worked answer
Any force must be necessary, proportionate and used only to prevent harm or effect a lawful purpose. The right to life creates a positive obligation to take reasonable steps to protect him, but that does not authorise excessive force. If he is detained under mental health powers, I need the legal criteria and an appropriate place of safety; a police cell is not automatically appropriate. If he is arrested to prevent harm, the grounds must be recorded. Taser could be an option if there is an immediate risk of serious harm, but it should be a last resort with a warning if feasible, and I must consider the risk of him falling or the knife causing injury. The negotiator should lead. I would record a decision log with times, information, options and rationale. I would also brief officers that if he jumps, the priority shifts to rescue and preservation of the scene. The reasoning is that the legal power is not the hard part; the hard part is justifying the least restrictive option in a fast-moving situation.
3. How do you manage the live-stream, the family and the media?
Read the worked answer
The live-stream is evidence and a risk. I would task an officer to monitor and record it, identify the platform and request preservation, but I would not try to shut it down by force or seize phones from the crowd without lawful grounds. I would ask spectators to stop filming and move back, and if they refuse, I would use the cordon and, if necessary, proportionate powers. For the family, I would assign a family liaison officer, take the mother's account of his mental state and medication, and keep her informed, but I would not let her negotiate unless the negotiator agrees. For the media, I would issue a short holding statement that avoids identifying him and asks for space. I would prepare for the possibility that the stream goes viral: no speculation, no images of the scene, and a welfare plan for the family. The reasoning is that the live-stream can escalate him and expose the family, but heavy-handed seizure would create a second crisis.
