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, as stated by police.
A 24-year-old man, was taken into custody in Lambeth for suspected robbery and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. Both individuals are still being held, the force said.
These detentions come after a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the attack, two women were robbed of their suitcases upon exiting a car park lift.
A three-year-old girl was among the those hurt in the event. Five people went to hospital for medical care and have since been released.
Police detained a man in his thirties for suspected theft and assault close to the location. He was subsequently released under investigation while inquiries continue.
Police were alerted at about 08:10 GMT after reports came in regarding a number of individuals hurt by an irritating chemical believed to be an irritant spray.
The attack - an event that authorities stated was isolated and not considered an act of terror - caused delays to rail services and the partial closure of the main airport tunnel and the T3 car park for a short time.
