An additional two individuals are now in custody related to a robbery at Heathrow Airport where 21 people sustained injuries by what is thought to be an irritant spray, as stated by police.
A man, 24, was taken into custody in Lambeth on suspicion of robbery and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. They both remain in custody, the force said.
The arrests come after an investigation into an assault at the multi-storey car park at Terminal 3 this past Sunday. Prior to the attack, 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. Five people were taken to the hospital for treatment and were later released.
Police arrested a 31-year-old man for suspected theft and assault near the location. He was subsequently released under investigation as the investigation proceeds.
Authorities were alerted at approximately 8:10 in the morning GMT following reports of several individuals injured by an irritating chemical believed to be pepper spray.
The assault - which police said was isolated 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 for a short time.
