Two more people are now in custody in connection with a robbery at Heathrow Airport where 21 people sustained injuries by a substance believed to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was arrested in Lambeth on suspicion of robbery and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. They both remain in custody, authorities confirmed.
These detentions come after an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers had stolen from them their suitcases upon exiting a car park lift.
A three-year-old girl was one of the injured in the event. A total of five individuals were taken to the hospital for treatment and have since been discharged.
Officers arrested a 31-year-old man for suspected theft and assault near the scene. 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 - an event that police said was isolated and not considered an act of terror - caused train delays and the partial closure of the Central Terminal Area tunnel and the T3 parking facility for a short time.
