Two more people are now in custody in connection with a theft at Heathrow Airport where 21 people sustained injuries by a substance believed to be an irritant spray, as stated by police.
A 24-year-old man, was taken into custody in the Lambeth area for suspected robbery and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
These detentions come after an investigation into an attack at the multi-storey car park at Terminal 3 on Sunday. Prior to the incident, two women were robbed of their suitcases after getting out of a car park lift.
A toddler aged three was one of the those hurt during the incident. Five people went to hospital for treatment and have since been released.
Police arrested a 31-year-old man for suspected theft and assault near the scene. He was subsequently released under investigation as the investigation proceeds.
Police were alerted at about 8:10 in the morning GMT after reports came in regarding several individuals hurt by a noxious substance thought to be pepper spray.
The assault - an event that 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 Terminal 3 parking facility briefly.
