Two more people have been arrested in connection with a robbery at London's 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 on suspicion of robbery and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. They both remain in custody, authorities confirmed.
These detentions follow a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the incident, a pair of female travelers had stolen from them their suitcases after getting out of a car park lift.
A toddler aged three was one of the injured in the event. Five people went to hospital for medical care and have since been released.
Officers detained a 31-year-old man on suspicion of theft and assault close to the location. He was subsequently released under investigation while inquiries continue.
Authorities were alerted at approximately 08:10 GMT after reports came in regarding several people hurt by an irritating chemical thought to be an irritant spray.
The attack - an event that authorities stated was isolated and not considered terrorism - caused train delays and the partial closure of the main airport tunnel and the T3 parking facility briefly.
