Two more people are now in custody related to a robbery at Heathrow Airport in which 21 people were injured by a substance believed to be an irritant spray, as stated by police.
A 24-year-old man, was taken into custody in the Lambeth area on suspicion of theft and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. They both remain in custody, authorities confirmed.
The arrests come after a probe into an assault at the multi-storey car park at Terminal 3 this past Sunday. Prior to the attack, two women were robbed of their suitcases after getting out of a parking garage elevator.
A three-year-old girl was among the those hurt during the incident. Five people were taken to the hospital for treatment and were later released.
Officers arrested a 31-year-old man for suspected theft and assault close to the location. He was subsequently released pending further inquiries while inquiries continue.
Authorities were called at about 08:10 GMT following reports of a number of individuals injured by an irritating chemical believed to be pepper spray.
The attack - which police said was isolated and not considered an act of terror - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
