An additional two individuals have been arrested related to a theft at 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 on suspicion of theft and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. Both individuals remain in custody, the force said.
The arrests follow an investigation into an assault at the multi-storey car park at Terminal 3 on Sunday. Prior to the incident, a pair of female travelers were robbed of their luggage upon exiting a car park lift.
A toddler aged three was among the those hurt in the event. A total of five individuals were taken to the hospital for treatment and were later discharged.
Police detained a 31-year-old man for suspected theft and assault close to the location. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were called at approximately 08:10 GMT following reports of several individuals hurt by an irritating chemical thought to be pepper spray.
The attack - an event that authorities stated was isolated and not being treated as terrorism - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park for a short time.
