Two more people have been arrested in connection with a theft at Heathrow Airport in which 21 people were injured by what is thought to be an irritant spray, according to law enforcement.
A man, 24, was arrested in Lambeth on suspicion of robbery and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. Both individuals remain in custody, the force said.
The arrests come after an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Before the incident, a pair of female travelers were robbed of their suitcases upon exiting a car park lift.
A toddler aged three was one of the those hurt during the incident. Five people went to hospital for treatment and have since been discharged.
Police detained a man in his thirties on suspicion of theft and assault close to the scene. He has since been released pending further inquiries as the investigation proceeds.
Police were alerted at about 8:10 in the morning GMT after reports came in regarding several individuals injured by a noxious substance thought to be an irritant spray.
The attack - an event that police said was isolated and not considered an act of terror - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the T3 parking facility briefly.
