An additional two individuals have been arrested in connection with a theft at London's Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be pepper spray, according to police.
A 24-year-old man, was taken into custody in Lambeth for suspected theft and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. They both remain in custody, authorities confirmed.
These detentions come after a probe into an assault at the multi-storey car park at Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers were robbed of their suitcases after getting out of a car park lift.
A toddler aged three was one of the injured in the event. Five people were taken to the hospital for treatment and were later released.
Police arrested a 31-year-old man for suspected robbery and assault near the location. He has since been released under investigation as the investigation proceeds.
Authorities were alerted at about 08:10 GMT following reports of a number of individuals injured by an irritating chemical believed to be an irritant spray.
The attack - an event that authorities stated was isolated and not being treated as terrorism - caused train delays and the partial closure of the main airport tunnel and the T3 parking facility briefly.
