Two more people are now in custody related to a theft at London's Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was arrested in the Lambeth area for suspected theft and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. Both individuals remain in custody, the force said.
These detentions come after a probe into an assault at the multi-level parking garage at Terminal 3 on 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 one of the those hurt in the event. Five people were taken to the hospital for treatment and have since been discharged.
Police arrested a 31-year-old man on suspicion of theft and assault near the scene. He was subsequently released under investigation while inquiries continue.
Police were called at approximately 08:10 GMT following reports of a number of people hurt by a noxious substance thought to be an irritant spray.
The attack - an event that authorities stated was isolated and not being treated as terrorism - resulted in train delays and the partial closure of the main airport tunnel and the Terminal 3 car park briefly.
