An additional two individuals are now in custody related to a robbery at Heathrow Airport where 21 people were injured by what is thought to be pepper 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 conspiracy to commit robbery. They both remain in custody, authorities confirmed.
These detentions come after a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the attack, a pair of female travelers were robbed of their suitcases upon exiting a car park lift.
A toddler aged three was among the injured during the incident. A total of five individuals were taken to the hospital for treatment and have since been released.
Officers detained a man in his thirties on suspicion of theft and assault close to the location. He was subsequently released under investigation while inquiries continue.
Authorities were alerted at about 8:10 in the morning GMT following reports of several individuals injured by a noxious substance thought to be an irritant spray.
The attack - an event that authorities stated was isolated and not being treated as terrorism - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
