Two more people are now in custody related to a robbery at London's Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be an irritant spray, according to law enforcement.
A man, 24, was taken into custody in Lambeth on suspicion of robbery and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. They both are still being held, authorities confirmed.
The arrests come after a probe into an attack 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 upon exiting a car park lift.
A toddler aged three was one of the those hurt in the event. A total of five individuals went to hospital for treatment and have since been released.
Police arrested a man in his thirties for suspected robbery and assault near the scene. He was subsequently released pending further inquiries while inquiries continue.
Authorities were alerted at approximately 08:10 GMT after reports came in regarding several people injured by a noxious substance believed to be pepper spray.
The attack - an event that police said was isolated and not considered terrorism - caused delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 car park briefly.
