Two more people are now in custody in connection with a theft at Heathrow Airport in which 21 people sustained injuries by a substance believed to be pepper spray, as stated by police.
A 24-year-old man, was arrested in the Lambeth area on suspicion of robbery and assault and a 23-year-old woman was arrested for suspected conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
These detentions follow a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers were robbed of their luggage upon exiting a parking garage elevator.
A three-year-old girl was among the those hurt during the incident. Five people went to hospital for treatment and have since been released.
Police arrested a man in his thirties for suspected robbery and assault close to the location. He has since been released under investigation as the investigation proceeds.
Police were alerted at about 8:10 in the morning GMT following reports of several individuals injured by an irritating chemical believed to be pepper spray.
The assault - an event that authorities stated was a standalone incident and not considered terrorism - caused train delays and the partial closure of the main airport tunnel and the Terminal 3 car park briefly.
