Two more people are now in custody in connection with a theft at London's Heathrow Airport in which 21 people were injured by a substance believed 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 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. Both individuals remain in custody, the force said.
These detentions follow a probe into an assault at the multi-level parking garage at Terminal 3 on Sunday. Before the attack, two women were robbed of their luggage after getting out of a car park lift.
A toddler aged three was one of the those hurt in the event. Five people went to hospital for treatment and were later discharged.
Police detained a man in his thirties for suspected theft and assault close to the location. He has since been released under investigation as the investigation proceeds.
Authorities were alerted at approximately 08:10 GMT following reports of several individuals injured by an irritating chemical thought to be an irritant spray.
The attack - an event that authorities stated was a standalone incident and not being treated as terrorism - resulted in train delays and the temporary shutdown of the main airport tunnel and the T3 parking facility briefly.
