Two more people are now in custody in connection with a theft at London's Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be pepper spray, as stated by police.
A man, 24, was arrested in Lambeth for suspected theft and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. They both remain in custody, the force said.
These detentions follow a probe into an assault at the multi-storey car park at Terminal 3 this past Sunday. Prior to the incident, a pair of female travelers were robbed of their luggage after getting out of a car park lift.
A three-year-old girl was among the those hurt in the event. A total of five individuals went to hospital for treatment and were later discharged.
Officers arrested a man in his thirties on suspicion of theft and assault close to the location. He was subsequently released pending further inquiries while inquiries continue.
Police were alerted at about 08:10 GMT after reports came in regarding a number of individuals injured by a noxious substance believed to be pepper spray.
The attack - which police said was a standalone incident and not being treated as terrorism - resulted in delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 parking facility for a short time.
