An additional two individuals have been arrested in connection with a robbery at Heathrow Airport in which 21 people were injured by a substance believed to be an irritant spray, according to law enforcement.
A man, 24, was arrested in Lambeth on suspicion of theft 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 attack at the multi-storey car park at Terminal 3 on Sunday. Prior to the attack, two women had stolen from them their luggage after getting out of a car park lift.
A three-year-old girl was among the those hurt during the incident. Five people went to hospital for medical care and have since been discharged.
Officers arrested a man in his thirties on suspicion of theft and assault near the location. He was subsequently released under investigation as the investigation proceeds.
Authorities were called at approximately 8:10 in the morning GMT following reports of a number of people hurt by an irritating chemical believed to be an irritant spray.
The attack - which authorities stated was a standalone incident and not being treated as terrorism - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility for a short time.
