An additional two individuals have been arrested in connection with a robbery at Heathrow Airport where 21 people sustained injuries by a substance believed to be an irritant spray, as stated by law enforcement.
A man, 24, was taken into custody in Lambeth on suspicion of robbery and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. They both remain in custody, authorities confirmed.
The arrests come after a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the attack, two women had stolen from them their suitcases upon exiting a car park lift.
A toddler aged three was one of the those hurt during the incident. Five people went to hospital for medical care and were later discharged.
Officers detained a 31-year-old man on suspicion of robbery and assault near the scene. He was subsequently released under investigation while inquiries continue.
Authorities were alerted at about 08:10 GMT following reports of a number of individuals hurt by an irritating chemical thought to be an irritant spray.
The attack - which authorities stated was a standalone incident and not considered terrorism - caused train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 car park briefly.
