Four men admit affray after a noxious substance sprayed at Heathrow Airport injures dozens of people. The incident occurs in a multi-storey car park at Terminal 3. Paramedics treat 21 people who are hit by CS spray, a chemical irritant. The BBC reports that all 21 are injured and that five people require further treatment in hospital. The Evening Standard similarly says paramedics treat 21 people affected by the spray in the multi-storey car park at Terminal 3. The men involved admit affray, an offence involving fighting or an act likely to cause a breach of the peace. Reporting across the outlets focuses on the number of people affected, the location within Heathrow, and the level of medical treatment needed, including hospital care for a subset of those injured. No further details about the circumstances of the spraying, the men’s identities, or the length of the court process are provided in the supplied excerpts.
