An additional two individuals have been arrested in connection with a theft at Heathrow Airport where 21 people sustained injuries by what is thought to be pepper spray, according to police.
A 24-year-old man, was arrested in the Lambeth area for suspected theft and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. They both remain in custody, the force said.
The arrests come after an investigation into an assault at the multi-storey car park at Terminal 3 this past Sunday. Before the attack, a pair of female travelers had stolen from them their suitcases after getting out of a parking garage elevator.
A three-year-old girl was among the injured during the incident. Five people were taken to the hospital for treatment and have since been discharged.
Police arrested a man in his thirties for suspected robbery and assault near the scene. He was subsequently released under investigation while inquiries continue.
Authorities were alerted at about 08:10 GMT after reports came in regarding several people hurt by an irritating chemical thought to be pepper spray.
The attack - an event that authorities stated was a standalone incident and not considered an act of terror - caused delays to rail services and the temporary shutdown of the main airport tunnel and the T3 parking facility briefly.
