Two more people have been arrested in connection with a theft at Heathrow Airport where 21 people sustained injuries by a substance believed to be an irritant spray, as stated by law enforcement.
A man, 24, was taken into custody in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. They both remain in custody, authorities confirmed.
These detentions come after an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the incident, a pair of female travelers were robbed of their suitcases after getting out of a car park lift.
A toddler aged three was one of the injured during the incident. Five people went to hospital for treatment and were later discharged.
Police detained a 31-year-old man on suspicion of theft and assault close to the location. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were alerted at approximately 8:10 in the morning GMT following reports of a number of people injured by a noxious substance thought to be an irritant spray.
The attack - which authorities stated was isolated and not being treated as terrorism - caused delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 parking facility for a short time.
