An additional two individuals are now in custody in connection with a theft at Heathrow Airport where 21 people sustained injuries by a substance believed to be pepper spray, as stated by police.
A man, 24, was taken into custody in the Lambeth area for suspected theft and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. Both individuals remain in custody, the force said.
These detentions follow a probe into an assault at the multi-storey car park at Terminal 3 on Sunday. Prior to the attack, two women had stolen from them their luggage upon exiting a parking garage elevator.
A three-year-old girl was among the injured during the incident. A total of five individuals 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 scene. He was subsequently released under investigation while inquiries continue.
Authorities were called at approximately 8:10 in the morning GMT after reports came in regarding several individuals hurt by an irritating chemical thought to be an irritant spray.
The attack - an event that police said was isolated and not being treated as terrorism - resulted in train delays and the temporary shutdown of the main airport tunnel and the T3 car park briefly.
