An additional two individuals have been arrested related to a theft at Heathrow Airport in which 21 people were injured by what is thought to be an irritant spray, according to law enforcement.
A 24-year-old man, was arrested in Lambeth for suspected robbery and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. They both remain in custody, authorities confirmed.
The arrests follow a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the attack, a pair of female travelers had stolen from them their luggage after getting out of a car park lift.
A three-year-old girl was among the those hurt during the incident. Five people went to hospital for medical care and were later released.
Officers detained a 31-year-old man for suspected theft and assault near the location. He was subsequently released pending further inquiries 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 assault - which authorities stated was a standalone incident and not considered an act of terror - caused train delays and the temporary shutdown of the main airport tunnel and the T3 parking facility briefly.
