An additional two individuals are now in custody related to a robbery at London's Heathrow Airport in which over twenty individuals were injured by a substance believed to be an irritant spray, as stated by police.
A 24-year-old man, was taken into custody in Lambeth for suspected robbery and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. Both individuals are still being held, the force said.
The arrests come after an investigation into an assault at the multi-storey car park at Terminal 3 on Sunday. Before the incident, 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 those hurt during the incident. A total of five individuals went to hospital for medical care and have since been discharged.
Officers arrested a 31-year-old man on suspicion of theft and assault near the location. He was subsequently released pending further inquiries while inquiries continue.
Authorities were alerted at about 8:10 in the morning GMT following reports of several individuals hurt by an irritating chemical believed to be pepper spray.
The attack - an event that authorities stated was isolated and not considered terrorism - caused train delays and the partial closure of the main airport tunnel and the T3 car park briefly.
