An additional two individuals are now in custody related to a theft at Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be an irritant spray, as stated by police.
A man, 24, was arrested in Lambeth on suspicion of theft and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. They both are still being held, authorities confirmed.
The arrests follow an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers had stolen from them their suitcases after getting out of a parking garage elevator.
A three-year-old girl was among the those hurt during the incident. Five people went to hospital for medical care and have since been released.
Police arrested a 31-year-old man on suspicion of robbery and assault near the scene. He was subsequently released pending further inquiries while inquiries continue.
Police were called at approximately 08:10 GMT after reports came in regarding several individuals hurt by an irritating chemical believed to be pepper spray.
The attack - an event that police said 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 for a short time.
