An additional two individuals are now in custody in connection with a theft at London's Heathrow Airport in which 21 people were injured 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 23-year-old woman was detained for suspected conspiring to commit a robbery. They both remain in custody, the force said.
These detentions come after 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 luggage after getting out of a car park lift.
A toddler aged three was among the those hurt during the incident. Five people went to hospital for medical care and were later discharged.
Officers arrested a man in his thirties on suspicion of theft and assault near the location. He was subsequently released pending further inquiries while inquiries continue.
Authorities were called at approximately 08:10 GMT after reports came in regarding several people hurt by an irritating chemical believed to be an irritant spray.
The assault - which authorities stated was isolated and not being treated as terrorism - caused train delays and the temporary shutdown of the main airport tunnel and the T3 car park briefly.
