An additional two individuals are now in custody related to a theft at London's Heathrow Airport in which 21 people sustained injuries by what is thought to be pepper spray, according to law enforcement.
A man, 24, was taken into custody in the Lambeth area for suspected robbery and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
These detentions come after 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 had stolen from them their suitcases after getting out of a car park lift.
A toddler aged three was among the injured in the event. Five people went to hospital for treatment and have since been released.
Police arrested a man in his thirties on suspicion of theft and assault near the location. He was subsequently released under investigation while inquiries continue.
Authorities were called at about 8:10 in the morning GMT after reports came in regarding several individuals hurt by a noxious substance thought to be pepper spray.
The assault - an event that authorities stated was isolated and not considered an act of terror - caused train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
