An additional two individuals have been arrested related to a theft at Heathrow Airport in which 21 people sustained injuries by what is thought to be pepper spray, according to law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area for suspected theft and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. Both individuals remain in custody, the force said.
The arrests come after an investigation into an attack at the multi-storey car park at Terminal 3 this past Sunday. Prior to the incident, a pair of female travelers had stolen from them their luggage after getting out of a parking garage elevator.
A three-year-old girl was among the those hurt during the incident. Five people were taken to the hospital for treatment and were later released.
Police arrested a 31-year-old man for suspected theft and assault near the scene. He was subsequently released under investigation while inquiries continue.
Authorities were alerted at approximately 08:10 GMT after reports came in regarding a number of people injured by an irritating chemical believed to be pepper spray.
The assault - which police said was a standalone incident and not considered an act of terror - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the T3 car park briefly.
