An additional two individuals are now in custody related to a robbery at Heathrow Airport where 21 people were injured by what is thought to be pepper spray, as stated by police.
A 24-year-old man, was taken into custody in the Lambeth area for suspected robbery and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. They both remain in custody, authorities confirmed.
The arrests follow a probe into an attack at the multi-level parking garage at Terminal 3 on Sunday. Before the attack, a pair of female travelers had stolen from them their suitcases after getting out of a car park lift.
A three-year-old girl was one of the those hurt in the event. A total of five individuals were taken to the hospital for medical care 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 pending further inquiries as the investigation proceeds.
Police were alerted at about 8:10 in the morning GMT after reports came in regarding several people injured by an irritating chemical believed to be an irritant spray.
The assault - which police said was isolated and not being treated as terrorism - caused delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 car park briefly.
