Two more people are now in custody related to a theft at Heathrow Airport in which 21 people were injured by what is thought to be an irritant spray, as stated by police.
A man, 24, was arrested in the Lambeth area on suspicion of theft and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. They both remain in custody, authorities confirmed.
The arrests come after an investigation 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 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. A total of five individuals went to hospital for medical care and have since been discharged.
Officers detained a 31-year-old man for suspected theft and assault near the scene. He was subsequently released under investigation while inquiries continue.
Police were alerted at approximately 8:10 in the morning GMT following reports of a number of individuals injured by an irritating chemical thought to be pepper spray.
The assault - an event that police said was a standalone incident and not being treated as terrorism - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 car park briefly.
