Two more people are now in custody in connection with a robbery at Heathrow Airport in which 21 people sustained injuries by what is thought to be an irritant spray, as stated by police.
A 24-year-old man, was taken into custody in Lambeth on suspicion of theft and assault and a 23-year-old woman was detained for suspected conspiring to commit a robbery. They both are still being held, the force said.
These detentions follow an investigation into an assault at the multi-storey car park at Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers were robbed of their luggage upon exiting a parking garage elevator.
A three-year-old girl was one of the injured during the incident. Five people went to hospital for treatment and have since been released.
Police arrested a 31-year-old man for suspected robbery and assault close to the location. He was subsequently released under investigation as the investigation proceeds.
Police were alerted at about 08:10 GMT after reports came in regarding several individuals hurt by an irritating chemical believed to be an irritant spray.
The assault - which authorities stated was a standalone incident and not considered an act of terror - caused delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 car park briefly.
