An additional two individuals are now in custody in connection with a theft at Heathrow Airport in which 21 people sustained injuries by what is thought to be pepper spray, according to law enforcement.
A 24-year-old man, was taken into custody in Lambeth for suspected theft and assault and a 23-year-old woman was arrested on suspicion of conspiring to commit a robbery. Both individuals are still being held, the force said.
These detentions come after a probe into an attack at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the incident, a pair of female travelers had stolen from them their suitcases after getting out of a car park lift.
A three-year-old girl was among the injured in the event. Five people went to hospital for treatment and were later discharged.
Police arrested a 31-year-old man on suspicion of theft and assault near the location. He was subsequently released pending further inquiries while inquiries continue.
Police were alerted at about 8:10 in the morning GMT following reports of several individuals injured by an irritating chemical believed to be an irritant 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 for a short time.
