Two more people are now in custody related to a robbery at Heathrow Airport where 21 people sustained injuries by a substance believed to be an irritant spray, as stated by law enforcement.
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. Both individuals remain in custody, the force said.
The arrests follow an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the incident, a pair of female travelers were robbed of their luggage upon exiting a parking garage elevator.
A toddler aged three was among the injured in the event. Five people went to hospital for medical care and were later released.
Police arrested a man in his thirties for suspected theft and assault close to the location. He was subsequently released under investigation while inquiries continue.
Authorities were called at about 8:10 in the morning GMT after reports came in regarding a number of people hurt by a noxious substance thought to be an irritant spray.
The assault - an event that police said was a standalone incident and not being treated as terrorism - caused delays to rail services and the temporary shutdown of the main airport tunnel and the T3 car park briefly.
