An additional two individuals have been arrested in connection with a robbery at Heathrow Airport in which 21 people sustained injuries by what is thought to be an irritant spray, as stated by police.
A 24-year-old man, was taken into custody in Lambeth on suspicion of theft and assault and a 23-year-old woman was detained for suspected conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
The arrests follow a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the incident, a pair of female travelers were robbed of their suitcases upon exiting a parking garage elevator.
A three-year-old girl was one of the injured during the incident. A total of five individuals were taken to the hospital for medical care and have since been released.
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 called at approximately 8:10 in the morning GMT following reports of several people injured by a noxious substance thought to be an irritant spray.
The attack - an event that police said was a standalone incident and not being treated as an act of terror - resulted in train delays and the partial closure of the main airport tunnel and the Terminal 3 car park for a short time.
