An additional two individuals are now in custody related to a theft at Heathrow Airport where 21 people were injured by a substance believed to be an irritant spray, as stated by law enforcement.
A man, 24, was arrested in the Lambeth area on suspicion of theft and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. They both are still being held, authorities confirmed.
These detentions come after a probe into an assault at the multi-storey car park at Terminal 3 this past Sunday. Prior to the incident, two women had stolen from them their luggage after getting out of a car park lift.
A toddler aged three was one of the injured during the incident. A total of five individuals went to hospital for treatment and have since been discharged.
Police detained a man in his thirties for suspected robbery and assault near the location. He has since been released under investigation as the investigation proceeds.
Police were alerted at about 08:10 GMT following reports of several individuals injured by an irritating chemical thought to be an irritant spray.
The attack - which authorities stated was a standalone incident and not considered an act of terror - caused train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
