An additional two individuals have been arrested in connection with a theft at Heathrow Airport in which over twenty individuals were injured by what is thought to be pepper spray, as stated by law enforcement.
A man, 24, was taken into custody in Lambeth on suspicion of robbery and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. They both remain in custody, authorities confirmed.
The arrests follow a probe into an attack at the multi-storey car park at Terminal 3 on Sunday. Before the incident, two women had stolen from them 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 have since been released.
Officers arrested a 31-year-old man on suspicion of theft and assault near the location. He was subsequently released pending further inquiries while inquiries continue.
Authorities were alerted at about 08:10 GMT following reports of a number of people injured by a noxious substance believed to be pepper spray.
The attack - which authorities stated was a standalone incident and not being treated as an act of terror - resulted in train delays and the partial closure of the main airport tunnel and the T3 car park briefly.
