Two more people are now in custody in connection with a theft at London's Heathrow Airport where 21 people sustained injuries by what is thought to be an irritant spray, according to police.
A 24-year-old man, was arrested in the Lambeth area for suspected theft and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit 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 this past Sunday. Before the attack, a pair of female travelers were robbed of their suitcases upon exiting a car park lift.
A three-year-old girl was one of the injured during the incident. A total of five individuals went to hospital for treatment and have since been discharged.
Police arrested a man in his thirties for suspected theft and assault near the location. He was subsequently released under investigation as the investigation proceeds.
Authorities were alerted at approximately 8:10 in the morning GMT after reports came in regarding several individuals hurt by a noxious substance believed to be an irritant spray.
The attack - which police said was a standalone incident and not being treated as terrorism - resulted in train delays and the partial closure of the main airport tunnel and the Terminal 3 parking facility briefly.
