Two more people are now in custody 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 arrested in the Lambeth area for suspected robbery and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. They both remain in custody, authorities confirmed.
The arrests follow a probe into an assault at the multi-level parking garage at Terminal 3 on Sunday. Prior to the attack, two women had stolen from them their suitcases after getting out of a parking garage elevator.
A toddler aged three was one of the injured during the incident. A total of five individuals went to hospital for medical care and have since been discharged.
Police arrested a man in his thirties on suspicion of theft and assault near the location. He has since been released pending further inquiries while inquiries continue.
Police were alerted at about 08:10 GMT after reports came in regarding several individuals injured by a noxious substance believed to be pepper spray.
The assault - which police said was a standalone incident and not considered an act of terror - resulted in delays to rail services and the partial closure of the main airport tunnel and the T3 parking facility briefly.
