An additional two individuals are now in custody in connection with a theft at London's Heathrow Airport in which 21 people were injured by what is thought to be pepper spray, as stated by law enforcement.
A man, 24, was arrested in Lambeth on suspicion of theft and assault and a 23-year-old woman was arrested on suspicion of conspiring to commit a robbery. They both remain in custody, the force said.
The arrests 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 upon exiting a car park lift.
A toddler aged three was one of the injured during the incident. A total of five individuals were taken to the hospital for treatment and have since been released.
Police detained a 31-year-old man on suspicion of theft and assault close to the location. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were called at about 08:10 GMT following reports of a number of individuals injured by an irritating chemical thought to be an irritant spray.
The assault - an event that police said was isolated and not being treated as terrorism - caused delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 car park for a short time.
