London’s Metropolitan Police say officers were called shortly after 8 a.m. on December 7 to Terminal 3’s car park following reports that a group of men had attacked people with what appeared to be pepper spray, leaving at least 21 needing treatment and five taken to hospital with non‑life‑threatening injuries. Police arrested one man on suspicion of assault and are searching for additional suspects who fled, while London Ambulance Service declared a “significant incident” and deployed multiple crews to the scene. Watch for details.
