An additional two individuals are now in custody in connection with a robbery at London's Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be an irritant spray, as stated by law enforcement.
A man, 24, was arrested in the Lambeth area for suspected theft and assault and a 23-year-old woman was detained for suspected conspiring to commit a robbery. They both remain in custody, authorities confirmed.
The arrests follow an investigation into an attack at the multi-storey car park at Terminal 3 on Sunday. Prior to the attack, two women had stolen from them their luggage upon exiting a car park lift.
A toddler aged three was among the those hurt in the event. A total of five individuals were taken to the hospital for treatment and were later discharged.
Police arrested a 31-year-old man on suspicion of theft and assault near the scene. He has since been released pending further inquiries while inquiries continue.
Authorities were alerted at about 08:10 GMT after reports came in regarding several people hurt by an irritating chemical thought to be an irritant spray.
The attack - an event that authorities stated was isolated and not being treated as terrorism - resulted in delays to rail services and the partial closure of the main airport tunnel and the T3 car park briefly.
