Two more people are now in custody in connection with a theft at 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 arrested in the Lambeth area on suspicion of theft and assault and a woman, 23 was arrested for suspected 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 incident, a pair of female travelers were robbed of their luggage after getting out of a car park lift.
A toddler aged three was one of the those hurt in the event. A total of five individuals went to hospital for treatment and have since been released.
Police detained a 31-year-old man for suspected theft and assault near 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 people injured by an irritating chemical believed to be an irritant spray.
The assault - which authorities stated was isolated and not considered an act of terror - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park briefly.
