An additional two individuals are now in custody related to a robbery at London's Heathrow Airport in which over twenty individuals were injured by what is thought to be an irritant spray, according to law enforcement.
A 24-year-old man, was taken into custody in Lambeth for suspected theft and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. They both remain in custody, authorities confirmed.
The arrests come after an investigation into an attack at the multi-storey car park at Terminal 3 on Sunday. Before the attack, a pair of female travelers were robbed of their luggage upon exiting a car park lift.
A three-year-old girl was one of the those hurt in the event. Five people went to hospital for treatment and were later discharged.
Officers detained a man in his thirties on suspicion of robbery and assault near the scene. He was subsequently released under investigation while inquiries continue.
Police were called at about 08:10 GMT after reports came in regarding several people injured by an irritating chemical believed to be an irritant spray.
The assault - an event that police said was a standalone incident and not considered an act of terror - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park briefly.
