Two more people have been arrested in connection with a theft at Heathrow Airport in which 21 people sustained injuries by a substance believed to be pepper spray, as stated by police.
A 24-year-old man, was arrested in Lambeth on suspicion of theft and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. They both are still being held, authorities confirmed.
These detentions come after a probe into an assault at the multi-storey car park at Terminal 3 on Sunday. Prior to the incident, two women had stolen from them their luggage upon exiting a car park lift.
A three-year-old girl was among the injured in the event. Five people went to hospital for medical care and have since been discharged.
Officers detained a 31-year-old man for suspected robbery and assault near the location. He was subsequently released under investigation while inquiries continue.
Authorities were called at approximately 08:10 GMT following reports of a number of people injured by a noxious substance thought to be pepper spray.
The attack - an event that police said was a standalone incident and not considered an act of terror - resulted in train delays and the partial closure of the main airport tunnel and the T3 parking facility for a short time.
