An additional two individuals have been arrested in connection with a robbery at Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be pepper spray, as stated by law enforcement.
A 24-year-old man, was arrested in the Lambeth area on suspicion of robbery and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
These detentions follow an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the attack, a pair of female travelers were robbed of their suitcases upon exiting a car park lift.
A three-year-old girl was among the injured during the incident. A total of five individuals went to hospital for treatment and were later discharged.
Officers detained a man in his thirties on suspicion of theft and assault near the location. He has since been released pending further inquiries while inquiries continue.
Authorities were called at approximately 08:10 GMT following reports of a number of individuals injured by an irritating chemical believed to be pepper spray.
The attack - which police said was a standalone incident and not considered an act of terror - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the T3 parking facility for a short time.
