Two more people have been arrested related to a theft at London's Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be pepper spray, as stated by police.
A 24-year-old man, was arrested in Lambeth for suspected robbery and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. They both remain in custody, the force said.
The arrests come after a probe into an attack at the multi-level parking garage at Terminal 3 on Sunday. Prior to the attack, a pair of female travelers were robbed of their suitcases after getting out of a car park lift.
A three-year-old girl was one of the those hurt during the incident. Five people went to hospital for treatment and were later discharged.
Police arrested a man in his thirties for suspected robbery and assault close to the location. He was subsequently released pending further inquiries while inquiries continue.
Authorities were alerted at approximately 08:10 GMT after reports came in regarding several individuals hurt by a noxious substance thought to be an irritant spray.
The assault - which authorities stated was a standalone incident and not considered terrorism - caused delays to rail services and the partial closure of the main airport tunnel and the T3 parking facility for a short time.
