Two more people are now in custody in connection with a robbery at Heathrow Airport in which over twenty individuals were injured by what is thought to be an irritant spray, according to law enforcement.
A man, 24, was arrested in Lambeth on suspicion of theft and assault and a 23-year-old woman was arrested for suspected conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
The arrests follow a probe into an attack at the multi-storey car park at Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers had stolen from them their suitcases after getting out of a parking garage elevator.
A three-year-old girl was one of the those hurt in the event. A total of five individuals went to hospital for medical care and were later released.
Officers detained a 31-year-old man on suspicion of robbery 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 following reports of a number of individuals injured by a noxious substance thought to be pepper spray.
The attack - an event that police said was isolated and not being treated as an act of terror - caused train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 car park briefly.
