An additional two individuals are now in custody in connection with a theft at Heathrow Airport in which 21 people were injured by a substance believed to be an irritant spray, according to police.
A 24-year-old man, was arrested in the Lambeth area for suspected robbery and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. They both remain in custody, authorities confirmed.
These detentions follow a probe into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers had stolen from them their luggage upon exiting a car park lift.
A toddler aged three was among the those hurt in the event. Five people went to hospital for treatment and have since been discharged.
Officers arrested a man in his thirties on suspicion of theft and assault close to the location. He has since been released pending further inquiries as the investigation proceeds.
Police were alerted at approximately 8:10 in the morning GMT following reports of several individuals injured by a noxious substance believed to be an irritant spray.
The attack - an event that authorities stated was isolated and not considered terrorism - caused delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 parking facility briefly.
