An additional two individuals are now in custody related to a theft at Heathrow Airport in which over twenty individuals were injured by a substance believed to be an irritant spray, as stated by law enforcement.
A man, 24, was taken into custody in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. They both remain in custody, authorities confirmed.
The arrests follow a probe into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the incident, a pair of female travelers were robbed of their suitcases after getting out of a car park lift.
A toddler aged three was among the injured during the incident. A total of five individuals were taken to the hospital for medical care and have since been released.
Officers detained a man in his thirties on suspicion of robbery and assault close to the scene. He has since been released pending further inquiries as the investigation proceeds.
Police were alerted at about 08:10 GMT after reports came in regarding a number of individuals injured by an irritating chemical thought to be an irritant spray.
The attack - which police said was a standalone incident and not considered an act of terror - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility briefly.
