Heathrow car park attack
On the morning of 7 December, emergency services attended a reported pepper-spray assault in the multi-storey car park at Heathrow Airport's Terminal 3.
“Police say 21 people were injured after reports of a "pepper spray assault" in the multi-storey car park at Heathrow Terminal 3 shortly after 08:10 on 7 December.”
The incident resulted in 21 people being treated for injuries, including a three-year-old girl, and five people were taken to hospital.
Police said the incident was reported shortly after 08:10/08:11, and a 31-year-old man was arrested on suspicion of assault and remains in custody.
Inquiries continue to locate further suspects, and the event prompted a rapid emergency response including armed officers and treatment by the London Ambulance Service.
Car-park dispute and theft
Police accounts in mainstream and local outlets describe the episode as sparked by an argument among people who knew each other and say it is not being treated as terrorism.
Several reports add that a woman's suitcase was stolen after suspects allegedly sprayed a substance believed to be pepper spray inside a car-park lift.
Authorities say they are reviewing CCTV and speaking to witnesses as they hunt for other suspects.
Heathrow emergency response
Emergency services treated people for coughing and throat irritation at the scene, and Heathrow staff handed out bottled water to stranded travellers.
“Witnesses reported coughing and throat irritation at the scene, and Heathrow staff later handed out bottled water to stranded travellers.”
The London Ambulance Service said 21 people were treated locally and five were taken to hospital, with injuries not believed to be life-changing or life-threatening.
Armed officers attended, and the first arrest was made within minutes of the call, with some reports specifying an arrest within nine minutes.
Heathrow travel disruption
The assault produced significant travel disruption around Heathrow.
Trains and buses to the airport were halted or diverted.
At least 17 trains serving Terminals 2 and 3 were cancelled or ran through.

By the time of reporting, outlets said services had largely returned to normal and Terminal 3 remained operational.
Heathrow urged passengers to allow extra time.
