An additional two individuals are now in custody in connection with a robbery at Heathrow Airport in which 21 people were injured by what is thought to be pepper spray, as stated by police.
A 24-year-old man, was taken into custody in Lambeth on suspicion of robbery and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. They both are still being held, authorities confirmed.
These detentions follow a probe into an attack at the multi-storey car park 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 toddler aged three was among the injured in the event. Five people went to hospital for treatment and were later discharged.
Police arrested a 31-year-old man on suspicion of theft and assault close to the location. He was subsequently released under investigation as the investigation proceeds.
Police were alerted at about 08:10 GMT after reports came in regarding several individuals injured by an irritating chemical thought to be an irritant spray.
The assault - an event that police said was a standalone incident and not considered an act of terror - resulted in train delays and the partial closure of the main airport tunnel and the Terminal 3 parking facility briefly.
