An additional two individuals have been arrested in connection with a theft at Heathrow Airport in which 21 people sustained injuries by what is thought to be pepper 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. Both individuals are still being held, authorities confirmed.
The arrests follow an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the attack, a pair of female travelers were robbed of their luggage after getting out of a car park lift.
A toddler aged three was one of the those hurt in the event. A total of five individuals went to hospital for treatment and have since been discharged.
Officers detained a man in his thirties on suspicion of theft and assault close to the location. He was subsequently released under investigation as the investigation proceeds.
Authorities were alerted at about 08:10 GMT after reports came in regarding a number of individuals injured by an irritating chemical thought to be an irritant spray.
The attack - an event that police said was isolated and not considered terrorism - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility briefly.
