An additional two individuals have been arrested in connection with a robbery at London's Heathrow Airport in which over twenty individuals were injured by what is thought to be an irritant spray, according to law enforcement.
A 24-year-old man, was arrested in Lambeth for suspected robbery and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. Both individuals are still being held, the force said.
The arrests follow a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the incident, two women had stolen from them their suitcases after getting out of a car park lift.
A toddler aged three was one of the those hurt during the incident. A total of five individuals went to hospital for treatment and were later released.
Police detained a man in his thirties on suspicion of theft and assault close to the location. He was subsequently released under investigation while inquiries continue.
Police were called at about 8:10 in the morning GMT after reports came in regarding a number of individuals injured by an irritating chemical believed to be an irritant spray.
The attack - an event that authorities stated was a standalone incident and not considered terrorism - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 parking facility briefly.
