An additional two individuals have been arrested related to a robbery at London's Heathrow Airport in which 21 people sustained injuries by what is thought to be an irritant spray, as stated by law enforcement.
A man, 24, was taken into custody in the Lambeth area for suspected robbery and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. They both are still being held, the force said.
The arrests follow a probe into an assault at the multi-storey car park at Terminal 3 on Sunday. Before the attack, 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 in the event. Five people were taken to the hospital for medical care and were later released.
Officers detained a man in his thirties on suspicion of robbery and assault near the location. He was subsequently released under investigation while inquiries continue.
Police were alerted at approximately 8:10 in the morning GMT after reports came in regarding a number of individuals injured by a noxious substance believed to be an irritant spray.
The attack - which police said was isolated and not considered terrorism - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
