Two more people are now in custody related to a theft at Heathrow Airport where over twenty individuals were injured by a substance believed to be an irritant spray, as stated by police.
A 24-year-old man, was arrested in Lambeth on suspicion of robbery and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. They both are still being held, the force said.
The arrests follow an investigation into an attack at the multi-storey car park at Terminal 3 on Sunday. Prior to the incident, a pair of female travelers had stolen from them their luggage upon exiting a car park lift.
A three-year-old girl was among the those hurt in the event. A total of five individuals were taken to the hospital for medical care and were later discharged.
Police arrested a 31-year-old man on suspicion of theft and assault near the scene. He has since been released pending further inquiries as the investigation proceeds.
Authorities were called at about 8:10 in the morning GMT after reports came in regarding a number of people injured by an irritating chemical thought to be an irritant spray.
The attack - an event that police said was isolated and not considered terrorism - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility for a short time.
