An additional two individuals are now in custody in connection with a theft at London's Heathrow Airport in which over twenty individuals were injured by what is thought to be an irritant spray, as stated by law enforcement.
A man, 24, was arrested in Lambeth for suspected theft and assault and a 23-year-old woman was arrested for suspected conspiracy to commit robbery. Both individuals are still being held, the force said.
These detentions follow an investigation into an assault at the multi-storey car park at Terminal 3 on Sunday. Before the incident, two women had stolen from them their luggage upon exiting a parking garage elevator.
A toddler aged three was one of the those hurt during the incident. A total of five individuals were taken to the hospital for medical care and were later discharged.
Officers detained a 31-year-old man for suspected theft and assault near the scene. He was subsequently released under investigation while inquiries continue.
Authorities were alerted at about 08:10 GMT after reports came in regarding a number of individuals injured by a noxious substance thought to be pepper spray.
The attack - an event that authorities stated was a standalone incident and not being treated as terrorism - caused delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 car park briefly.
