An additional two individuals are now in custody related to a theft at London's Heathrow Airport in which 21 people sustained injuries by what is thought to be pepper spray, as stated by law enforcement.
A 24-year-old man, was taken into custody in Lambeth on suspicion of theft and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. They both remain in custody, the force said.
The arrests 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 had stolen from them their luggage 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 discharged.
Police detained a 31-year-old man for suspected theft and assault near the location. He was subsequently released under investigation as the investigation proceeds.
Authorities were called at approximately 8:10 in the morning GMT after reports came in regarding a number of people hurt by a noxious substance believed to be pepper spray.
The assault - an event that police said was a standalone incident and not being treated as an act of terror - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility briefly.
