An additional two individuals are now in custody related to a robbery at Heathrow Airport in which 21 people were injured by what is thought to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was arrested in the Lambeth area on suspicion of theft and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. They both remain in custody, authorities confirmed.
The arrests follow an investigation into an attack at the multi-storey car park at Terminal 3 on Sunday. Before the attack, a pair of female travelers had stolen from them their suitcases upon exiting a parking garage elevator.
A three-year-old girl was one of the injured during the incident. A total of five individuals were taken to the hospital for treatment and were later released.
Officers detained a 31-year-old man for suspected theft and assault near the scene. He was subsequently released pending further inquiries while inquiries continue.
Police were alerted at about 08:10 GMT after reports came in regarding a number of individuals hurt by an irritating chemical thought to be an irritant spray.
The assault - an event that police said was a standalone incident and not being treated as terrorism - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility briefly.
