An additional two individuals are now in custody related to a robbery at Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was arrested in Lambeth on suspicion of theft and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. They both remain in custody, the force said.
The arrests follow a probe into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the attack, a pair of female travelers had stolen from them their suitcases after getting out of a parking garage elevator.
A toddler aged three was among the injured in the event. A total of five individuals went to hospital for treatment and were later discharged.
Police arrested a man in his thirties on suspicion of robbery and assault near the scene. 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 individuals injured by an irritating chemical thought to be pepper spray.
The attack - which authorities stated was isolated and not being treated as terrorism - caused delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility briefly.
