Two more people are now in custody related to a theft at Heathrow Airport where 21 people sustained injuries by what is thought to be an irritant 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 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. They both are still being held, authorities confirmed.
These detentions come after an investigation into an attack at the multi-level parking garage at Terminal 3 on Sunday. Prior to the incident, a pair of female travelers had stolen from them their luggage after getting out of a parking garage elevator.
A toddler aged three was among the injured during the incident. A total of five individuals went to hospital for treatment and were later discharged.
Officers arrested a 31-year-old man on suspicion of robbery and assault near the location. He was subsequently released under investigation while inquiries continue.
Authorities were alerted at approximately 08:10 GMT after reports came in regarding a number of individuals injured by an irritating chemical believed to be pepper spray.
The attack - which authorities stated was a standalone incident and not being treated as an act of terror - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 car park briefly.
