An additional two individuals are now in custody related to a theft at Heathrow Airport where over twenty individuals sustained injuries by what is thought to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was arrested in Lambeth for suspected robbery and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. They both remain in custody, the force said.
The arrests follow a probe into an assault at the multi-level parking garage at Terminal 3 on 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 among the injured during the incident. Five people were taken to the hospital for treatment and were later discharged.
Police detained a man in his thirties for suspected theft and assault near the scene. He has since been released pending further inquiries while inquiries continue.
Police were called at about 8:10 in the morning GMT after reports came in regarding a number of people hurt by an irritating chemical believed to be an irritant spray.
The assault - which authorities stated was a standalone incident and not being treated as terrorism - caused delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 car park for a short time.
