An additional two individuals are now in custody in connection with a theft at Heathrow Airport in which over twenty individuals were injured by a substance believed to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was arrested in Lambeth for suspected theft and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
The arrests follow an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the attack, two women had stolen from them their suitcases upon exiting a parking garage elevator.
A three-year-old girl was one of the those hurt during the incident. Five people were taken to the hospital for treatment and have since been released.
Officers detained a 31-year-old man for suspected theft and assault close to the scene. He has since been released pending further inquiries as the investigation proceeds.
Police were called at about 8:10 in the morning GMT following reports of several individuals injured by an irritating chemical believed to be an irritant spray.
The attack - an event that police said was isolated and not considered terrorism - resulted in train delays and the partial closure of the main airport tunnel and the Terminal 3 car park for a short time.
