An additional two individuals 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, according to police.
A 24-year-old man, was taken into custody in Lambeth for suspected theft and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. They both remain in custody, authorities confirmed.
These detentions come after an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the incident, a pair of female travelers were robbed of their luggage upon exiting a car park lift.
A toddler aged three was among the injured during the incident. Five people went to hospital for treatment and have since been released.
Officers detained a 31-year-old man for suspected robbery and assault close to the location. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were alerted at about 08:10 GMT after reports came in regarding several individuals hurt by a noxious substance thought to be pepper spray.
The attack - which police said was a standalone incident and not being treated as terrorism - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park for a short time.
